PRODUCT FAQs
Bulbs: Standard
My bulb is not working. What do I do?
There are several troubleshooting steps you can take:
1. Check the bulb - Sometimes a poor contact between the light base and the fixture can cause issues with the flow of an electric current. Make sure your bulb is firmly tightened in the light socket. Also, ensure the screw base of your light fixture is not corroded.
You can also check the bulb in another, compatible light fixture that you know is working.
2. Check the fixture - Remove the bulb and replace it with a bulb that you know works in a similar fixture. Screw in the 2nd light bulb and turn on the light. If the 2nd light does not work, continue to Step #3 and #4.
If the 2nd bulb works (and you are not using a dimmer or timer), then it is possible the 1st bulb is somehow at fault. Please review the rest of the troubleshooting steps before contacting customer service. We stand by our products and provide an industry leading warranty, so you don’t have to worry about malfunctions. Please contact our Customer Service Specialists for additional help, if these steps do not fix the issue.
3. If you are using a timer using add-ons (such as timers, photo controls or occupancy sensors) - Sunco LED bulbs and retrofit downlights are not designed to be compatible with photo controls, occupancy sensors or timing devices. Please remove the timer or use the D2D bulb in another light fixture without a timer.
4. Check dimmer compatibility - There are multiple types of dimmers available on the market that will function with dimmable Sunco LEDs. First, confirm your bulb is dimmable by viewing the tech specs on our Manuals & Documentation page. You can also view our dimmer compatibility list for each dimmable product. Drill down to find the product, then click on the green button to view the dimmer list.
NOTE: Smart Bulbs are dimmable without a dimmer, when using the app paired with a compatible smart phone or tablet with WiFi. Dusk to Dawn and Motion Activated lights are not dimmable.
Why is my LED bulb or retrofit downlight not working with my timer?
Sunco LED bulbs and retrofit downlights are not designed to be compatible with photo controls, occupancy sensors or timing devices.
What does Damp rated and Wet rated mean?
The words damp and wet in our product tech specs refer to moisture ratings. Safety is the main reason why damp/wet ratings matter.
Learn more about it in our blog Choosing LED Damp vs. Wet Rated Lights. You may also be interested in our blog on Why IP Ratings are Important, where you can see a diagram of bathroom safety zones.
My lights pop on to a bright level instead of turning on normally. What do I do?
This can sometimes be an issue with the dimmer switch. The dimmer cannot always be turned on to the lowest level first. Instead, slide the dimmer switch above the minimum level, then turn on the light. You can then reduce the light to a minimum level by lowering the slider.
Why does it take a long time for my LED bulb to go dark when I turn it off? What can I do about afterglow?
Afterglow, where the bulb stays illuminated after the power is disengaged sometimes happens with LED bulbs. Be reassured that this slight glow will not affect the quality or the lifetime of your bulb.
Afterglow happens when the LED driver stores electrical energy. The glowing can last from seconds to minutes. Please confirm you are using a compatible dimmer switch. We also recommend you consult with a certified electrician in your area.
Why are my LED lights flickering?
LED bulbs can flicker or buzz when the current isn’t constant. There are several troubleshooting steps you can take if you are experiencing a flickering light:
1. Check the bulb - Sometimes a poor contact between the light base and the fixture can cause issues with the flow of an electric current. Make sure your bulb is firmly tightened in the light socket. Also, ensure the screw base of your light fixture is not corroded.
2. Check the fixture - There may be a loose wire or connection in your light fixture. Select another bulb of the same type (one that is working properly elsewhere), then test it in the same socket/fixture. If that second bulb works, then move on to step 3. If not, examine the wire connection between the bulb and circuit. If wires are loose or about to disconnect/break this can cause a flickering.
3. Check dimmer compatibility - Buzzing or flickering may indicate that the dimmer is not compatible with the light bulb. We highly recommend using an ELV (electronic low voltage) LED dimmer from our list of compatible dimmers in our Manuals & Documentation page.
4. For smart bulbs - If you are using a dimmer with a smart bulb and are experiencing buzzing or flickering, please plug that light fixture into a circuit without a dimmer. Sunco LED Smart Bulbs do not need a dimmer. You can control the dimming via your smart phone or tablet with and app over WiFi.
5. For appliances - Make sure that any fans or other high power drawing appliances are not connected to the same circuit as your LED light bulbs.
Why are my LED lights buzzing?
Buzzing LED lights indicates several possible issues:
1. Check the circuit - If you are running multiple lights on the same circuit, it is possible that you need to disconnect some to not overload the circuit. Too much draw could cause the current to not be constant, which can cause buzzing.
2. Check dimmer capacity - For multiple LED bulbs attached to a dimmer, verify the wattage supported by your dimmer. You don’t want to overload the circuit and may need to disconnect some to see if this solves the problem.
3. Check dimmer compatibility - Buzzing or flickering may also indicate that the dimmer is not compatible with the light bulb. We highly recommend using an ELV (electronic low voltage) LED dimmer from our list of compatible dimmers in the Manuals & Documentation page.
4. Mixed bulb types - Avoid mixing traditional and LED style bulbs in the same light fixture. Traditional bulbs such as incandescent, halogen, or CFLs use more power than LEDs and this can sometimes cause a varying current so that the LED won’t function properly.
NOTE: Our bulbs are FCC certified. The buzzing you hear is not due to radio interference.
Can I install your LED Corn Bulb horizontally?
Yes, you can. However, a vertical install will place less stress on the bulb base than a horizontal installation would.
My LED light bulb won’t turn off completely when I turn off the switch. There is a permanent afterglow or a ghost. What can I do?
Your light bulb is experiencing afterglow when it won’t turn off completely and stays lit, even after you turn off the power switch. Since you are describing a permanent condition, you likely have a switch or dimmer that was connected incorrectly, or unfavorable cable routing, or circuitry that is too old to properly regulate the electrical current. The result is that the LED bulb is operating on lower power than what is normally flowing in the circuit.
Did you recently convert to LED light bulbs from traditional bulbs? Often this issue is only visible when a change to LED is made, though the circuitry issue was still present. Traditional bulbs include a filament that would not be able to light up with leaking currents or induced voltages, while your LED bulb uses less wattage and can glow weakly on low voltage currents.
Please confirm you are using a compatible dimmer switch. We also recommend you consult with a certified electrician in your area to investigate any other issues that might cause this.
If I increase voltage or wattage does the light get brighter?
No, brightness is determined by the lumen count. Volts and watts are not a brightness rating.
Lumens indicate the amount of brightness a bulb emits in all directions. They are usually written in technical specifications like this: 4500LM or 4500lm. The higher the number, the brighter the bulb.
The brightness of a light is not determined by the amount of electricity flowing through a circuit (volts) or how much energy is consumed (in watts). If you increase the voltage supplied to your product that will lead to the bulb burning out similar to a power surge (and voiding your warranty).
Bulbs: Portable & Emergency
How do I charge the A21 Emergency LED Bulb?
Simply screw the rechargeable A21 Emergency Bulb into a suitable light fixture with an E26 socket. After 5 hours, the bulb will be fully charged.
I cannot turn off the A21 Emergency LED Bulb. Why is the bulb always on?
Normally this will not happen, however some complex circuit systems can cause this instance to occur. This issue happens across the board with different manufacturers sometimes.
Possible solutions here include:
- It is possible that some residual voltage on the line is triggering the light bulb to remain on. Incandescent bulbs do not have this issue, as it takes more power to illuminate them. LEDs use less power and can trigger with less input. You can potentially solve this issue by plugging in multiple lights to the same circuit (within stated limits of the circuit). Some residual voltage could be absorbed that way. If you experience the same issue after implementing the suggested fix, please consult a qualified electrician for additional solutions.
- You may have an issue within the electrical circuits. Please consult a qualified electrician.
How come my A21 Emergency LED Bulb is not as bright when using with a battery as it is when inside a light fixture?
When the A21 Emergency LED Bulb is connected to a light fixture it produces 1100 lumens of bright light for your general purposes lighting needs. When disconnected, the bulb draws power from the built-in, rechargeable battery. It will produce only 150 lumens in order to provide you with up to 4 hours of portable light.
How long does it take to charge the battery included in the A21 Emergency LED Bulb?
Charge the A21 Emergency LED Bulb in a lamp with the power and light switch flipped on for approximately 5 hours.
When the bulb is charged, it will last as a flashlight or pendant light for up to 4 hours.
Bulbs: Bug Lights
Why is my Yellow Bug Light LED Bulb not working with my timer?
Sunco LED Yellow Bug Lights are not designed to be compatible with photo controls, occupancy sensors or timing devices.
Bulbs: Dusk to Dawn
Why does spacing matter with Dusk to Dawn (D2D) light bulb?
Sunco Dusk to Dawn LED lights include a built in photocell sensor to detect light levels. This turns on the LED in absence of light and off again when light is detected.
Spacing is needed between multiple Dusk to Dawn (D2D) light bulbs or wall packs so that the light of one will not interfere with another. This prevents light from shining on the sensor of a nearby D2D bulb. Otherwise, it is possible that existing light could fool the D2D sensor into thinking it is daytime and it won’t turn on when it should.
To help you avoid this issue, please use the proper spacing provided below when mounting your Dusk to Dawn lights.
Dusk to Dawn PAR20, PAR30, PAR38 Bulbs
Space D2D PAR bulbs used as downlights or uplights at least 0.5 meters (1.64 ft) apart so they do not interfere with one another.
You can also consider:
1. Pointing lights away from one another so their beams to do not strike nearby light fixtures and the D2D sensor.
2. Using a dual bulb fixture with bulbs pointing in different directions (usually affixed to the side of a wall or in landscaping as uplights and washes).
Dusk to Dawn Wall Packs
Our LED Wall Packs with Dusk to Dawn perform best when mounted at least 16.4 ft (5m) from a wall, at least 32.8 ft (10m) from another D2D Wall Pack or other light source, and at least 9.84 ft (3m) from the ground.
Recommended Spacing:
- • 9.84 ft (3m) from the ground
- • 16.4 ft (5m) from a wall
- • 32.8 ft (10m) from another Wall Pack
ST64 D2D & A19 D2D Bulb
Sunco's A19 LED bulb detects infrared (IR) light. Spacing concerns should only appear when placing more than one A19 LED Bulb in the same fixture.
Why is my Dusk to Dawn (D2D) light not working near my garage or a window?
Sunco Dusk to Dawn LED lights include a built in photocell sensor to detect light levels. This turns on the LED in absence of light and turns it off again when light is detected.
Reflective surfaces can fool the Dusk to Dawn sensor into thinking there is sufficient light available, so the light turns itself off.
When installing in an area with a reflective floor, shiny surface, or a window, we recommend you install the product higher than the reflection or window. This will reduce the chances that it might mimic another light source and fool the built in sensor.
In addition, PAR Dusk to Dawn lights work best in non-reflective cans. The reflective nature of chrome style cans sometimes fools the sensor so that your light will turn on (when no light is detected), then the reflected light reaches the sensor and it goes off again, then it turns on again when no light is detected in a continuous loop.
Why does my Dusk to Dawn (D2D) light turn off, then on, then off again repeatedly?
Sometimes reflective surfaces can fool a Dusk to Dawn sensor into thinking there is sufficient light available, so the light turns itself off. It then registers no light detected and turns itself back on. This continues in a loop of off/on/off/on so that the light can appear to be strobing or flashing.
In addition, PAR Dusk to Dawn lights work best in non-reflective cans. The reflective nature of chrome style cans sometimes fools the sensor in this same fashion.
Consider these potential solutions:
1. Point lights away from one another so their beams to do not strike the D2D sensor in nearby light fixtures.
2. Use a dual bulb fixture with bulbs pointing in different directions (usually affixed to the side of a wall, below a roofline, or in landscaping as uplights and washes).
3. Move a light fixture above a garage window or away from a doorway window will reduce the chances a reflective surface might mimic a light source and fool the D2D sensor.
Why won’t my Dusk to Dawn (D2D) light turn on?
Sunco Lighting Dusk to Dawn LED light bulbs include a built in photocell sensor which controls the electric current to operate the LED, based on available light levels. This turns on the LED in absence of light and turns it off again when light is detected.
Dusk to Dawn bulbs are designed for exterior use. They work only at night.
Consider these potential solutions:
- Check the Power - In order for a Dusk to Dawn LED to turn on, the light fixture it is screwed into or the circuit a Wall Pack is connected to needs to be turned on. If no electricity is flowing, then the sensor cannot adjust when light is present or absent.
- Check the sensor – The photocell sensor needs to be exposed or open to detect light. This means your light fixture should not block the sensor, which sits just above the base of the light bulb.
- Check beam spread - Ensure that no other light beam is hitting the photocell sensor, which might fool it into thinking that there is light and therefore it would not illuminate.
- Check the Bulb - Try the LED in another light fixture or on another circuit you know to be functioning. The light should turn on in the absence of light. If the Dusk to Dawn light still does not illuminate, when no light is available and there is power to the light fixture or wall pack, then please contact our Customer Service Specialists.
We stand by our products and provide an industry leading warranty so you don’t have to worry about malfunctions. Each of our products are tested to meet industry standard and are backed by certifications to ensure optimal performance and safety.
What about Dusk to Dawn Infrared?
PIR or Passive Infrared technology includes an electronic sensor that detects motion by infrared (IR) objects or bodies within range of the sensor. That would include humans, dogs, and other animals, since we radiate heat. Note that the sensor detects a change in radiation levels, rather than looking at average IR levels.
When connected to an LED light bulb or LED tube light fixture, a PIR sensor detects a certain range of radiated heat or what is called infrared radiation. When the sensor detects a change in radiation within its tolerance levels, it will turn on the light. After motion stops, the light will turn itself off within a certain, set time period.
For example, Sunco Lighting’s motion activated PAR38 Dusk to Dawn bulbs light up when movement is detected and turn off 25 seconds after movement ceases. These are ideal security lights for commercial and residential homes.
Bulbs: Motion Activated
How do PIR motion activated lights work?
Without going into the technical weeds of this topic, PIR or Passive Infrared technology includes an electronic sensor that detects motion by infrared (IR) objects or bodies within range of the sensor. That would include humans, dogs, and other animals, since we radiate heat. Note that the sensor detects a change in radiation levels, rather than looking at average IR levels.
When connected to an LED light bulb or LED tube light fixture, a PIR sensor detects a certain range of radiated heat or what is called infrared radiation. When the sensor detects a change in radiation within its tolerance levels, it will turn on the light. After motion stops, the light will turn itself off within a certain, set time period.
- Sunco Motion Activated Shop Lights are designed to turn off after 10 minutes, when detected motion (radiation levels) stop. These lights are ideal for storage areas, basements, and infrequently used hallways, among other applications.
- Sunco’s motion activated PAR38 Dusk to Dawn bulbs light up when movement is detected and turn off 25 seconds after movement ceases. These are ideal security lights for commercial and residential homes.
Also note that PIR motion activated LED bulbs should not be placed inside an enclosed fixture; it works best with open bulb design styles.
In addition, PIR sensors can be affected by extreme hot or cold weather. During intense heat, the sensor may not detect the moving heat signature from a passing person or animal due to the overall heat detected. During extreme cold weather, the sensor may be fooled into turning on with motion on a sunny day due to the variances between the cold surroundings and a passing person or animal.
If you are using these near sidewalks with frequent foot traffic, for example where a neighbor might walk a dog near your property, you can angle the light beam down and away from high traffic areas so that lights are not flashing on off unless needed on your property.
Other terms for this type of motion activation include: Pyroelectric and IR motion.
Bulbs: Smart Bulbs
Why is the White brighter on my smart bulb than when I choose an RGB color?
What your eyes are seeing is a different way to view the light and is not a defect of the bulb. The lumen output of each smart bulb applies to the Correlated Color Temperature (CCT) scale, 2700K to 5000K for instance, and does not apply to the RGB (rainbow colors) output. On some RGB colors, the brightness is slightly lowered to retain color saturation and enhance the color.
Smart bulbs are designed with tunable white light for bright illumination are ideal for task lighting. RGB colors to help you establish an ambiance or mood.
CCT is a way to measure a light’s appearance in the warm or cool tones of the light emitted. You can learn more about color temperature in our blogs, Color Temperature Applications and Kelvin Levels Explained or The Color of Light & CCT. You can also learn more about the properties of light in our blog Understanding the Visible Light Spectrum and Color.
Do your LED smart bulbs include programmable scenes to customize my lighting?
Yes, with LED Smart Bulbs from Sunco you can either use the preset scenes or else define your own light settings and save it to use your favorite scenes later when you use the app with your smart device.
Our installation manual explains how to control your lighting. You can find the install manual on the product page under Support or in our Manuals and Documentation page.
How do I program LED smart bulbs to turn the light on/off on a set schedule?
Using your smart phone, the app, and Sunco LED smart bulbs you can set a schedule to turn your light on/off at set times. You can choose individual actions for each bulb, set the same schedule for more than one day, and create a schedule for a group of bulbs.
Our installation manual explains how to control your lighting. You can find the install manual on the product page under Support or in our Manuals and Documentation page.
Do Sunco LED smart bulbs work with voice activation?
Yes! Sunco LED Smart Bulbs can be voice-activated with Amazon Alexa and Google Assistant. Now you can tell your lights what to do and have them change your lighting on command. Get ready to say “OK Google” and “Alexa…” a lot, as you play with all the lighting options available with these smart bulbs.
Our installation manual explains how to control your lighting. You can find the install manual on the product page under Support or in our Manuals and Documentation page.
How many LED Smart Bulbs can I group together at one time?
Sunco LED Smart Bulbs can be set up for Automation in the Smart Life app. An automation scenario allows you to group up to 150 LED Smart Bulbs together, so you can control up to 150 LED Smart Bulbs at the same time.
Need help with that? Please contact our Customer Service team.
I am having issues with smart bulb connectivity. What do I do?
First of all, so sorry you are experiencing issues when connecting your smart bulb. We hope to help you fix that. Please review the following:
Connectivity and Router - Confirm your router is dual-band. Select 2.4G network.
Additional Router Info to Check:
- Your router, the smart bulb, and your phone with the App should be within range of one another.
- Ensure signal strength is medium signal and no less than -60dB.
- Wireless Router Setup – Set encryption method as WPA2-PSK and authorization type as AES or you can set it as AUTO. Wireless mode cannot be 11n only.
Voice Control - If you are attempting to control your smart bulb by restarting your ALEXA or GOOGLE device.If the Smart Life App isn’t working for you as expected, you can also pair Sunco Smart Bulbs with the Tuya App instead.
If the steps above do not resolve your issue and you are using the Tuya App, please contact TUYA directly through the help section of the App.
If you prefer, you can contact us and provide this information so we can help you:
- Device ID:
- APP Account:
- Issue Occurrence Time:
- Batch Code (monthyear) printed on the bulb:
Do smart bulbs need to be near a router to work?
Sunco LED Smart Bulbs work in combination with your WiFi router and an app on your smart phone or compatible smart device. When you select 2.4G network on your dual-band router, the reach is up to 150 feet indoors. Please position your router in a central location of your home or office. We recommend you place the router on a second floor for a 2-story home.
Note that if there are multiple walls between the router and the smart bulb and your app this may affect router signal strength and your connectivity. In that instance, a WiFi extender is recommended.
What is tunable white?
Tuning allows you to change the warm vs. cool quality of a light to create the white light quality you want and need with your LED Smart Bulb.
The conventional design of LED Smart Bulbs is that white light is used for task lighting (reading, cleaning, etc.) while RGB is used to establish atmosphere and mood. The lumen count you see on the Lighting Facts label and our product spec sheet for each Sunco LED Smart Bulb applies to the CCT scale (2700K-5000K) and not to RGB output. RGB brightness (lumen count) is therefore lower than when you select the color white in the Smart Life App for your LED smart bulbs.
Can I synchronize my LED lights to music?
Yes! With LED Smart Bulbs from Sunco you can synch your lights to music so that the LED Smart Bulb changes color to the music beat. Each of our smart bulbs can animate in rhythm with the music you play in the same room. The music sync function is ideal for a party setting and much more.
For best results when using the music sync setting, keep your phone in the room near the audio source and the app open.
Our installation manual explains how to control your lighting. You can find the install manual on the product page under Support or in our Manuals and Documentation page.
Ceiling Panels
There are 2 wiring compartments on the back of the Sunco LED Ceiling Panel. Why is that?
Our LED Ceiling Panels include two driver covers on the back of the panel. One holds the wiring to power the light itself. That one should include a black wire (L), white wire (N), and green wire (ground). The other one includes wires to connect your compatible dimmer, if you want to add one. Dimmers are not included when you purchase the light.
The Sunco LED Ceiling Light Panel fixture is dimmable via 0-10V dimming. Originally, 0-10V dimming was used as a standard means to control fluorescent dimming ballasts. You can use it on some drivers on LED lights, including this one.
On LED lights, 0-10V dimming controls LED output intensity to change how much light is emitted.
What does a Class 2 circuit mean?
A Class 2 circuit is a low voltage circuit located between the load side of a Class 2 power source and the connected equipment. The power supply in this case would convert 120V power into low voltage.
The National Electric Code (NEC) Article 725 designates Class 1, 2, 3 wiring details. Class 2 wiring uses conductor sizes 18 AWG or 16 AWG. Class 2 provides acceptable protection from an electric shock and is considered to be safe from fire risk.
Do I have to install the LED Ceiling Panel in a drop ceiling or can I suspend it?
Either type of install is possible with our LED Ceiling Panel Light.
- Drop Ceiling Install - Mount it flush against a drop ceiling.
- Suspension Install - Suspend from a wire so it hangs horizontally away from the ceiling. Suspension kits are not included with the panel, but they would include an anchor, wire rope, and hardware.
Please visit our Documents & Manuals page to download the install manual PDF for more details both methods to mount this LED fixture.
How do I secure the LED Ceiling Panel to a drop ceiling?
Your LED Ceiling Panel comes with protective brackets on the back of the panel. These bright, metal “L” shaped pieces are flush against the light panel for easy transport.
Simply bend each piece up 90° and then twist to the hook portion faces the outside edge of the Ceiling Panel.

For full installation details, please visit our Documents & Manuals page to download the install manual PDF.
Dimming
Can I dim your LED lights?
Many of the Sunco LED bulbs and lamps offered on this website will dim. The product descriptions and technical specifications for each individual product will include that information for your reference. You can also find it under our Manuals & Documentations page.
Dimming tech specs are usually shown in this format: 100%-10%, meaning that it will dim down to 10%. The bulb will turn off below the 10% dim setting.
Dimmers are not included with Sunco products. You need to purchase those separately, unless stated otherwise.
Which dimmers are compatible with your lights? Do you sell Dimmers?
There are multiple types of dimmers available on the market that will function with Sunco LEDs, but Sunco does not sell dimmers. Visit our Manuals & Documentation page to view our dimmer compatibility list for each dimmable product. Drill down to find the product you plan to buy, then click on the green button to view the dimmer list.
Smart Bulbs are dimmable without a dimmer, when using the app paired with a compatible smart phone or tablet with WiFi.
Dusk to Dawn and Motion Activated lights are not dimmable.
If you need more information, please contact our Sales Team.
Dimming is not working for me. What do I do?
There are a few troubleshooting steps you can take to remedy this:
1. Select another bulb of the same type (one that is dimming properly elsewhere), then test it in the same socket/light fixture. This should verify whether there are any loose wires in your fixture or if the dimmer itself is not working properly.
2. If you are experiencing a buzzing or flickering light, this indicates that the dimmer is not compatible with the light bulb. We highly recommend using an ELV (electronic low voltage) LED dimmer from our list of compatible dimmers in the Manuals & Documentation page.
3. If your product is under warranty, and is not resolved by steps 1 and 2, please contact our Customer Service Specialists at 844-334-9938 or email support@suncolighting.com. It helps to provide a photo of the product or a video. That way we can quickly help you verify the issue and how we can resolve it.
Can you save energy with modern dimmers and dimmable LEDs?
Yes, dimming a dimmable LED bulb can save you energy with the use of modern dimmers.
Many dimmers on the market can deliver reduced energy consumption when you lower the level of your lights. That’s because when you dim a bulb you are reducing the flow of electricity to it. If an LED bulb draws less power, then it consumes less energy.
Dimmers can extend the life of your LED bulb, so you can conserve even more.
What is 0-10V Dimming?
On LED lights, 0-10V dimming controls LED output intensity to change how much light is emitted (i.e., 1V is 10%). 0-10V dimming allows you to scale the output of your dimmable LED light to create the lowest dimming level possible.
Can I use Sunco dimmable products with 2- and 3-way dimmers?
Please refer to the compatible dimmer list, found in the support tab for each dimmable product or visit our Manuals & Documentation page to find your product.
Exit Signs
Can you wall mount and ceiling mount the LED exit sign?
Yes, you can choose to either wall mount or ceiling mount Sunco’s LED Exit Sign.
The installation guide will walk you through this process. You can find the install manual on the product page under Support or in our Manuals and Documentation page. There are also some visual diagrams on the product page regarding the easy installation.
Mounting equipment is included inside the fixture. Note that when you ceiling mount the sign, you need to use the extension that is also stored inside the fixture for your convenience.
Please check building regulations in your region to verify any mounting or location requirements.
Do I need to charge Sunco’s LED Exit Sign built in battery?
Yes, the included battery for your LED Exit Sign may not be fully charged. After electricity is connected to the unit, the included battery needs 24 hours to charge before performing tests or using it as an emergency light during power failure.
The Exit Sign should be hardwired to your building’s electricity so that the emergency mode will activate (and use the battery) in case of a power outage.
Can I adjust the lamp heads on the LED Exit Sign?
Yes, there are two lamp heads on each Sunco LED Exit Sign. You can rotate the adjustable lamp heads and also tilt them up and down. The bright flood lights swivel up to 350° so you can customize to suit each location.
Are your LED Exit Signs one or two sided?
You can modify Sunco LED Exit Signs to be one or two sided by adding the included second face plate to the housing. Simply unsnap the housing to open the fixture, then insert the second face plate into the housing.
How do I adjust the directional arrows on the LED Exit Sign?
Directional arrows on the LED Exit Sign allow you to point to the left and/or right of the sign. These arrows snap out so you can customize each sign. Open up the sign and pop out the directional arrows, as appropriate for each location.
How do I test the LED Exit Sign?
To test, press the “TEST” button located on the side of the LED Exit Sign. The button is a momentary switch that disconnects the power when you depress it to put the Exit Sign temporarily into Emergency Mode. The sign should illuminate, using the built in battery (once it has been charged).
Remember that you are required by law to test your exit and emergency lighting on a regular basis. Please check regulations for how often this should be done and properly maintain your emergency lighting.
On your LED Exit Sign, will the batteries recharge after power returns?
Yes, once power returns to your building the hardwired Exit Sign will recharge the battery. It takes around 5 hours for the battery to recharge to allow for up to 90 minutes of battery powered light during an emergency.
Is the battery already connected on your 2 Floodlight Exit Sign?
All the wiring is in place to power the rechargeable battery, but you need to connect the battery for it to charge.
Unsnap the face plate to open.

Connect the battery to the socket inside, then snap the face plate back in place.

Remember to test the exit sign 24 hours after charging the battery before relying on this in an emergency.
How do I open up the LED Exit Sign?
Press down on the top/edge of the LED Exit Sign housing, next to the paired indentation marks, but not on the indentations. At the same time, open by gently pulling on the lip with the paired marks. This will release one side of the front or rear. Repeat this step to release the other side.
Both front and back of the LED Exit Sign open so you can create a one sided or two sided sign.
What is a UL 94V-0 Rating?
This UL rating means that the light fixture will not act as a fire promotor to further spread flames, due to its certified fire resistance and self-extinguishing characteristics.
Our Exit Signs are made of ABS fire resistant plastic. The UL 94V-0 rating is based off a product test that involves burning the vertical part of a product to check whether it will extinguish itself after 10 seconds.
You can learn more about all the certifications and the companies that certify our products in our Certifications page.
I want to use the light up directional arrows, but there is plastic blocking the light. What do I do?
The plastic you see covering the directional arrows are called knockouts. Simply pop out the directional arrows, as appropriate for your light fixture location.
Remove the faceplate/cover then pop the plastic piece(s) out to reveal the backlit red arrow, when appropriate.
- Leave the directional arrow knockouts in place when you do not need a lit arrow.
- Remove them when you require an arrow to help point the way to safety.
Base this decision on where you mount the light fixture so the arrows can point the way to a safety exit to the left or right of the sign.
General
Do you sell waterproof bulbs?
Yes, some of the LED products in our inventory are Wet rated and suitable for the outdoors.
If you are designing an exterior lighting plan and want wet rated bulbs, check out our blog, Choosing LED Damps vs. Wet Rated Lights for more information. It will help you understand what are wet rated lights, and why moisture ratings matter.
If you are designing an interior space with moisture rating concerns, like a bathroom, there is a blog on explaining Why IP Ratings are Important that includes a diagram to help you with wet/damp lights in a bathroom.
Sunco indicates the UL Listing of moisture ratings in the technical specs, so you know our products meet the set standards.
What is the lifetime hour expectation of an LED bulb or tube? How long do LEDs really last?
Compared to traditional light bulbs and fluorescent light tubes, LEDs have a long lifespan. Some can last up to 50,000 lifetime hours.
Each Sunco product includes the lifetime hours in our technical specifications. You’ll also find it in the standard Lighting Facts Label for each bulb. You can learn more about the Lighting Facts Label in our Footer under the Quick Links.
While the Lighting Facts Label calls out power usage and lifetime hours based on a 3 hour day, we recognize that you will likely use your light bulb more frequently. When you compare even 25,000 lifetime hours on an A19 LED Bulb vs. a 1,500 hour average life span of an A19 incandescent bulb that is a huge savings for you.
Where are your products manufactured and are you based in the United States?
While our manufacturing partners are based overseas and produce the products we sell to our specifications and requirements, Sunco Lighting is based in the United States. We are American owned and operated.
You will find the country of origin printed on our products and packaging, per FTC requirements.
What does Integrated LED mean?
With integrated LEDs, the LED is included as part of the light fixture. You will not need to relamp an integrated light fixture during its lifetime.
Sunco offers these integrated LEDs:
- LED T5 Integrated Fixture
- LED Industrial Shop Light, Frosted
- LED Flat Shop Light, Clear
- LED Utility Shop Light, Clear
Sunco also offers a recessed lighting Integrated Slim with J-Box in two sizes:
And what about Retrofit LED?
Retrofit LEDs are replacement bulbs or downlights that fit into existing light fixtures. They are typically a replacement for outdated traditional bulbs. Here are Sunco’s retrofit LEDs:
What about fire ratings?
Sunco's luminaires are evaluated to UL 1598 for the standard safety certification, however there isn't a fire rating requirement at this time.
If you need a fire-rated luminaire, specified by building codes, there are several "fire-rated" ceiling designs that specify standard luminaires can be installed without impacting the overall fire rating.
Please contact us with further questions.
What about fire resistance?
Sunco Exit Signs are designed for use during a power failure, which can sometimes be caused by a fire. Our LED Exit Signs are made of ABS fire resistant plastic. Most are UL 94V-0 rated. This UL rating means that the light fixture will not act as a fire promotor to further spread flames, due to its certified fire resistance and self-extinguishing characteristics.
The UL 94V-0 rating is based off a product test that involves burning the vertical part of a product to check whether it will extinguish itself after 10 seconds.
Please contact us with further questions.
I am having dirty power problems. Can I stop dirty power from affecting my LED lights?
Dirty power is when the power consistently fluctuates outside the acceptable range (usually 60Hz and +/-6V from 120V). You see this with flickering and blinking lights, breaker tripping, transformer issues, along with household equipment vibrations and noise. You may have referred to the issue as surges, spikes, lags, dips, transients, or power interruptions. All of this disrupts technology’s functionality.
If you are trying to identify the issue, you cannot rely on just a voltage meter or current measurements to examine the power quality. Consulting with an electrician is the best solution. They may locate potential improper wiring or irregular grounding issues, among other issues. However, if you live in a rural area your delivered power may be dirty at your home or business.
There are a few solutions to try:
- Book an electrician consult. They will assess the problem in your home with appropriate meters and suggest solutions.
- Add an uninterruptible power supply (UPS) so you can maintain power during input power failures.
- Plug LED lights and traditional incandescent bulbs into separate circuits.
- Investigate whether there are overloaded circuits or if using less items on the circuit improves the situation.
- Stop using dimmers switches for your lights. Try LED smart bulbs instead.
- Limit use of fans, variable-speed appliances, and microwaves.
- When not in use, turn off your household technology.
- Improve power quality with power factor correction, voltage stabilization, high frequency filters, harmonic filters, or line reactors.
General: Color Temperature
What color temperatures do you offer?
Sunco color temperatures include:

Sunco LED products include a variety of color temperatures to choose from. Your selection will vary based on the bulb or fixture type.
Remember, the lower the temperature, the warmer the look; the higher the temperature, the cooler the look. If you want to learn more about color temperatures, please check out these two blogs:
What do you mean by Daylight?
Despite the term referring to sunlight and the outdoors, when a bulb is defined with the word "Daylight" it is not referring to whether you can use that bulb in your exterior lighting or exposure to the elements. Daylight also does not mean an LED light bulb is wet rated. Daylight in regards to LED lighting refers to color temperature.
Sunco’s Daylight bulbs are 5000K, which is the closest color temperature to mimic natural sunlight.
If you are designing an exterior lighting plan and want damp or wet rated bulbs, check out our blog, Choosing LED Damps vs. Wet Rated Lights for more information. There is also a blog on explaining Why IP Ratings are Important that includes a diagram to help you with wet/damp lights in a bathroom plan.
If you want to know more about color temperature, check out our blog, Color Temperature Applications and Kelvin Levels Explained or The Color of Light & CCT to learn more about that. You can also learn more about the properties of light in our blog Understanding the Visible Light Spectrum and Color.
Grow Lights
Can I surface mount your grow light or just suspend from chains?
Yes, to both. You can either suspend our grow light fixtures from the provided chain to install it or you can surface mount it.
Please review the install manual to follow the installation steps for your particular grow light. Installation manuals are located on our Manuals & Documentation page.
What is a Full Spectrum Grow Light?
Indoor growers rely upon grow lights that mimic the UV rays of the sun in the form of LED full spectrum grow lights. As an indoor gardener, utilizing the entire Visible Light Spectrum (often referred to in marketing as Full Spectrum for grow lights) provides an artificial light source to promote plant growth during all stages of development.
Serious growers and experts have done studies that show you can produce a bigger/ healthier harvest with full spectrum grow lights, along with a high yield. Full Spectrum grow lights can improve flowering/blooming, cloning, vegging, and seeding stages.
The added bonus of using an LED grow light is that you also save energy when lighting your hydroponic garden or large grow application, due to the lower wattage consumed when compared to traditional bulbs.
If you are curious about the Visible Light Spectrum itself, and what light humans can see, you can examine our blog, Understanding the Visible Light Spectrum and Color to learn more
High Bays (Linear)
Which methods can I use to install your Linear High Bay LED light fixtures?
Our LED Linear High Bay fixtures (110W, 160W, 220W options) include V hooks and hanging chains for a fast installation of these suspended area lights. The easy installation manual shows you the chain mounting method.
High Bays (UFO)
My UFO High Bay is flickering. What do I do?
Turn off the power to your UFO High Bay. Wait 3 minutes. Turn it on again.
Is it connected to a dimmer? These LED fixtures only work with 1-10V dimming.
If it still flickering, please contact our Customer Service team.
What does a Class 1 circuit (signaling) mean?
A signaling system is used to illuminate a light or signal equipment to turn on an audio signal, such as a bell or horn. Sunco’s UFO High Bay uses a Class 1 Signaling circuit to illuminate the LED.
The National Electric Code (NEC) Article 725 designates Class 1, 2, 3 wiring details. A Class 1 circuit (signaling) can operate up to 600V. It is located in the wiring between the load side of a circuit breaker or fuse (an overcurrent device) and the connected equipment. It is installed in a conduit or protective cable assembly, such as a racetrack, for safety.
Class 1 circuits allow for more power than Class 2, which runs on low voltage. That means Class 1 circuits can accommodate more LEDs and are more effective than Class 2 drivers.
Recessed Lighting: General
Do I need a J-Box or a recessed Can?
The choice between recessed can or junction box often comes down to the type of space where you are installing the downlight. To select either a J-Box or a Recessed Can, you should examine your needs, the space where you will be placing the downlight, and how the downlight will secure in that space.
If you are looking to fit in a small space or adjust to joists that are right beside where you want your downlight, please consider a Slim or a Slim with Integrated J-Box.
What junction box and recessed can are designed to do:
Junction boxes (J-boxes) are designed to:
- Protect, secure, and enclose wiring connections to prevent physical damage
- May act as a mounting mechanism
- Prevent live wires from accidental contact with device wiring for both fire safety reasons and to prevent electrical shock
Recessed cans cover the same issues above, but in different ways:
- Include an enclosed, complete housing (the housing/can itself)
- Acts as a mounting mechanism
- No wire leads extend outside of it, unless contained inside wiring conduit, such as in our Remodel Cans and New Construction Cans.
Sunco Recessed Cans and Downlight Types:
New Construction – Recessed cans of this type are designed to be surrounded by insulation in a ceiling when they are IC rated like those offered by Sunco. They are installed into framing during new construction or new build out of a building. Secures to the framing with bar hangers prior to installing drywall and ceiling materials. Does not include an LED light. Sunco’s fixture does include a J-Box.
Remodel – Remodel recessed light cans are inserted into ceilings that are already installed. For your convenience, a J-Box is included in Sunco’s remodel can. These units are smaller in height than the New Construction style. Remodeling clips secure the can in the roof or overhead joist space into ceiling drywall or plaster. Does not include an LED light. Sunco’s fixture does include a J-Box.
Slims (with J-Box or Integrated J-Box) – Offers a thin profile for remodeling or in tight ceiling spaces, such as beside joists. Some of Sunco’s slims fit within a 2” minimum height clearance! Can be metal or plastic J-box. Typically secures with spring brackets in ceiling.
Disk Downlights – Similar to slim, except that it does not include a J-Box. Sunco Disks are direct wired to your junction box. Includes metal wire brackets to install in a can, if preferred. Could also install directly to the ceiling.
Retrofit Downlights – New Construction and Remodel Cans do not include LED lights or J-boxes. You can add LED retrofit downlights in 4/5/6-inch cans. Typically secures with metal mounting bracket. Some are adjustable between 5” and 6” cans by modifying the placement of a screw to fit.
Installed correctly, our IC Rated recessed lighting can be placed adjacent to insulation in ceiling spaces without fire issues.
NOTE: Electrical regulations may vary by region. Please speak with a qualified, professional electrician or contractor to confirm requirements regarding your unique installation.
What type of trim styles do you offer for recessed LEDs and Slim downlights and what is the benefit of each trim type?
We offer two types of trim styles for recessed LEDs and Slim downlights:
What do “Baffle” and “Smooth” trim mean?
Baffle and smooth refer to the trim style for our Slims and Retrofit downlights. Smooth trim is suitable for a streamlined, modern look. Baffle trim features uniformed grooves close to the light source to minimize glare and create a soft light. Softer light tends to be less straining on your eyes.
A recessed can won’t fit next to the joists where I want a downlight. What should I used instead?
Our Slim downlights fit well in small ceiling spaces and around joists.

With the Sunco Slim Downlights, you can easily secure a downlight on either side of a joist (see photo above), while the J-Box sits nearby.
Our Slims securely connect to the included J-Box with an included wire. The flexible wire between the J-Box to the Slim allows you to position the spring brackets of the LED around a joist and then place the J-Box nearby.
By comparison with a recessed can, you might be unable to secure the can in place, since the joist might be in the way of the mounting brackets.
I have a new building and want to install LED recessed lighting. What do you recommend?
Recessed Cans for New Construction are ideal for this scenario. You can choose from 4” Recessed Cans or 6” Recessed Cans. These cans secure to the joist via included bar hangars. A TP24 connector is included to connect whichever LED downlight you choose to pair with this can. A J-Box is included.
If you just took over a new office building or home and want to add new cans into a finished ceiling, you will want our Remodel Cans instead. These secure via mounting clips to your ceiling, once inserted into the hole you will cut to size. A J-Box is included.
You can also use our line of Slim LED Downlights. Sunco Slims include a junction box and do not need a recessed can to install them in a ceiling. Some are integrated with a J-Box and some include the J-Box separate from the LED unit so you can place the slim near joists or in narrow ceilings. Both types are an All in One package for a fast install.
I am having clip or spring issues with my recessed light. Can you help?
Yes, we can help. Here are some troubleshooting steps you can take:
- Back plate clips - A flathead screwdriver can help you snap the spring into place. Simply insert the flat screwdriver so the tip opens the spring ring, then insert the plate.
- Silver-plated clips – Use a screwdriver to adjust your spring sizing. Loosen, then slide the screw to the desired size and tighten.
Having additional troubles with your spring or clips? We uphold the highest standards for all our products by testing each product for optimal performance and safety. Our goal is to exceed customer expectations as well as market standards, but we also understand that issues do arise.
Our industry-leading product warranty means you don't have to worry about malfunctions and can have confidence that all of our products will meet their expected lifetime.
Please reach out to our Customer Service Specialists so we can help provide a seamless customer experience.
What about recessed lighting fire ratings?
Sunco's luminaires are evaluated to UL 1598 for the standard safety certification, however there isn't a fire rating requirement at this time.
If you need a fire-rated luminaire, specified by building codes, there are several "fire-rated" ceiling designs that specify standard luminaires can be installed without impacting the overall fire rating.
Please contact us with further questions.
I’m installing recessed lighting. Are there any restrictions on insulation?
We currently have two styles of Slim downlights in our warehouse: metal and sturdy plastic junction boxes. The new style of plastic J-Boxes should not be installed in polystyrene foam (whether board or bead/loose fill style). As a precaution we recommend you do not use polystyrene foam insulation, because it can catch fire at 150° F, whereas other insulation types catch fire at 400° F (UL/ETL test for IC rating includes this).
In addition, be sure to wear protective gloves when maintaining any recessed cans, Slims with J-Boxes, or retrofit downlights. The recommendation to wear gloves also applies to handling any plastic parts, since human skin has a lower heat tolerance level and the durable plastics used in our recessed LED lights can run at 90° F.
Installed correctly, our IC Rated recessed lighting can be placed adjacent to insulation in ceiling spaces without fire issues.
What LED driver is in your canless recessed lights?
Our canless recessed led lights operate on a constant current driver to keep the LED at the exact voltage it requires.
Recessed Lighting: Cans
What is New Construction vs. Remodel?
Recessed cans come in different styles. Sunco recessed cans are designed to be surrounded by insulation in a ceiling when they are IC rated, like those offered by Sunco.
Recessed Cans do not include an LED light. You will need to purchase those separately.
New Construction –Installed into framing during new construction or new build out of a building. They secure to framing with bar hangers, prior to installing drywall and ceiling materials.
Remodel – Remodel recessed light cans are inserted into ceilings that are already installed, often in existing holes for downlights. For your convenience, a J-Box is included in Sunco’s remodel can. These units are smaller in height than the New Construction style. Remodeling clips secure the can in the roof or overhead joist space into ceiling drywall or plaster.
What size LED bulbs fit in a recessed can?
This handy chart shows which PAR or BR bulb type you can pair with each size of recessed can.
Unsure which you want, because you don’t know what kind of light PAR LED Bulbs or BR LED Bulbs produce? We have a blog to help you: What is the Difference Between PAR and BR Bulbs.
NOTE: Sunco Lighting Recessed Cans include a TP24 connector. They are not compatible with an E26 base bulb. We recommend our Retrofit Downlights or Disk Downlights instead of a bulb (see list below).

How do I secure an LED retrofit downlight to an existing can?
Our Recessed Lighting are secured via Spring Connectors that clip into existing holes in the can. The product manuals provided (also available for download) can further assist you with the installation process.
What LED driver is in your retrofit downlights?
Our retrofit LED downlights operate on a constant current driver to keep the LED at the exact voltage they require.
Do any Sunco LED Retrofit Downlights require a special breaker or will standard work?
There are no special requirements for our LED downlights regarding breaker compatibility.
If you are concerned about overloads or have older wiring, you could consider using an AFCI or Arc-Fault Circuit Breaker or a CAFI / CAFCI Combination Arc-Fault Breaker.
Are Sunco LED Retrofit Downlights compatible with both CAFCI breakers and AFCI breakers?
Sunco LED retrofit downlights are compatible with both CAFCI (CAFI) Combination Arc-Fault Breakers and AFCI/Arc-Fault Circuit Breakers.

What size hole should I cut in the ceiling to fit your 4” or 6” LED Slim Downlight?
A hole in the ceiling is required to insert the junction box (J-Box). Our LED Slim Downlights require these hole sizes for installation, based on the Slim type:
- 4” Slim = 4.33” hole
- 6” Slim = 6.3” hole
This applies to the Sunco’s standard Slim and the Integrated Slim with J-Box.
How do I link your Slim Downlights?
Please consult with a qualified professional electrician regarding your circuit and dimmer capacities to ensure it fits your setup.
There is no ground wire in the recessed light I received.
We currently have two styles of Slim downlights in our warehouse. We are phasing out the metal junction boxes. Metal J-Boxes are conductive and require a ground wire to prevent electric shock in the case of accidental leakage.
Our new style of recessed Slim LED includes a durable plastic J-Box. Plastic is not conductive, so it’s safe to touch and a ground wire is not required. This is why UL and ETL certifications have no ground wire design requirements for plastic electronic equipment.
Are Sunco LED Slims compatible with both CAFCI breakers and AFCI breakers?
Sunco Slims are compatible with both CAFCI (CAFI) Combination Arc-Fault Breakers and AFCI/Arc-Fault Circuit Breakers.
Do any Sunco LED Slims require a special breaker or will standard work?
There are no special requirements for our LED downlights regarding breaker compatibility.
If you are concerned about overloads or have older wiring, you could consider using an AFCI or Arc-Fault Circuit Breaker or a CAFI / CAFCI Combination Arc-Fault Breaker. Please also consult with a licensed electrician with additional questions.
How many Sunco Slims can be linked on a 15-amp breaker?
The Sunco 6” Slims each have 0.125A.
For a 15-amp breaker, you want to only use about 80-85% of the breaker capacity for safety reasons, in case the breaker cannot sustain the full 15A.
In an ideal situation, you would calculate 12/0.125=96 pieces.
FOR REFERENCE re: full circuit capacity
In an ideal situation you would calculate 15/0.125=120pc.
My 6-pack of LED Slims does not include Junction Boxes. I thought they were included.
It may not look like it at first glance, but the Slim downlights with Junction Boxes shipped to you in a 6-pack box do include junction boxes. They are located below the cardboard that is cushioning the LED light itself. Simply lift up that cardboard sheet to reveal the additional compartment with your junction boxes.
Sconces and Wall Lights
Can I dim lights in your wall sconces?
Yes, if the wall sconce is not labeled as a Dusk to Dawn sconce, then you can add a dimmable bulb to the sconce and connect a compatible dimmer.
Be sure to confirm the wattage acceptance for each sconce prior to screwing in a new light bulb.
NOTE: The ST64 LED Filament Bulb that comes with the Avalon Caged Wall Sconce and the Avalon Caged Wall Sconce Dusk to Dawn is not dimmable.
Can I replace the ST64 LED Filament bulb in your Avalon Caged Wall Sconce?
Yes, you can. Our Avalon Caged Wall Sconce accepts an E26 base light bulb maximum of 20 watts.
NOTE: The Avalon Caged Wall Sconce Dusk to Dawn cannot accept a bulb that is Dusk to Dawn, since the fixture itself includes a dusk to dawn sensor and they would not function together. You only need the sensor on the wall sconce for Dusk to Dawn functionality.
What kind of bulb can I use in your wall sconces?
Our Wall Sconce family accepts both LED and traditional light bulbs (refer to wattage consumption below). Note that any wall sconce with Dusk to Dawn functionality cannot accept a bulb that is Dusk to Dawn, since the fixture itself includes a dusk to dawn sensor and they would not function together. You only need the sensor on the wall sconce.
Here is a list of the maximum wattage accepted by our wall sconces, along with other bulb requirement details.
Avalon Caged Wall Sconce with ST64 Filament Bulb
- E26 Base
- 20W maximum
- Dimmable (with compatible dimmer, not included) or Non-Dimmable

NOTE: Please use a bulb without Dusk to Dawn capabilities for any wall sconce that is labeled as Dusk to Dawn. The fixture itself has a Dusk to Dawn sensor so you do not need a dusk to dawn bulb for it to automatically turn on/off with detected light levels.
Why won’t my Dusk to Dawn bulb work in your wall sconce?
Most of our wall sconces include a Dusk to Dawn sensor on the sconce. This means that the sconce cannot accept an additional Dusk to Dawn sensor on a bulb. Please use a bulb without Dusk to Dawn capabilities.
Security Lights
Can I change how long your 3 Head Security LED Light will stay on? Are there time settings?
Yes, there are three time settings to choose from: 30 seconds, 60 seconds (1 minute), 120 seconds (2 minutes) on the Sunco 3 Head Security LED Light. When motion stops, the auto motion sensor on the light will automatically turn off after the time setting you selected.
So, if you choose 30 seconds, the light turns on when it detects motion. When the motion stops, the light will turn off after 30 seconds has passed.
Can I adjust the motion sensitivity on your 3 Head Security LED Light?
Yes, you can establish the motion detection range on the Sunco 3 Head Security LED Light. There are three possible modes to choose from:
- 13ft – 20ft (2m – 6m)
- 20ft – 33ft (6m – 10m)
- 33ft – 49ft (10m – 15m)
The installation manual for this light will explain how to determine which distance will work best for your situation. You can find our installation manuals on the Manuals & Documentation page.
Shoeboxes
Can I adjust my Shoebox LED Parking Lot Light Fixture?
Yes, our Shoebox LED Parking Lot Light uses an AM mount, an adjustable slip fitter mount for round poles. The angle adjusts up to 90-degrees.
Simply loosen and tighten the adjusting bolt in the back to aim the light beam where you need it.

If you install the Shoebox fixture with a yoke (not included), it may only adjust up to 35-degrees.
What does a Class 1 circuit (signaling) mean?
A signaling system is used to illuminate a light or signal equipment to turn on an audio signal, such as a bell or horn. Sunco’s Shoebox light uses a Class 1 Signaling circuit to illuminate the LED.
The National Electric Code (NEC) Article 725 designates Class 1, 2, 3 wiring details. A Class 1 circuit (signaling) can operate up to 600V. It is located in the wiring between the load side of a circuit breaker or fuse (an overcurrent device) and the connected equipment. It is installed in a conduit or protective cable assembly, such as a racetrack, for safety.
Class 1 circuits allow for more power than Class 2, which runs on low voltage. That means Class 1 circuits can accommodate more LEDs and are more effective than Class 2 drivers.
Shop Lights
Do your shop lights chain mount or flush mount?
Most Sunco shop lights can be either chain mounted or direct mounted. We wanted you to be able to choose how to hang your light fixture so you can either surface mount or suspension mount your shop lights.
The only exceptions are:
- Chain Only: LED Flat Shop Light
- Flush Mount Only: LED Wraparounds
Check each product page to see the components included and the styles available to suit your specific needs.
What are SEP Single Ended Power Tubes?
Unlike outdated fluorescent bulbs that are dual end powered (DEP), Sunco LED T8 Tubes are Single Ended Power (SEP). This refers to how the electrical current runs through the tube.
DEPs tend to use shunted tombstones or sockets to hold a fluorescent tube in place. When you switch to T8 LED Tubes (SEP) from traditional tubes, you may need to change the sockets to non-shunted tombstones. It depends on how your current light fixtures are wired.
Unsure what you have in existing shop light fixtures and whether you need SEP vs DEP tubes? Check out our blog on what type of Socket do I need (Shunted vs. Non-Shunted) to learn more.
What is direct wire?
When you direct wire a shop light (sometimes called hardwired), you are not connecting the plug to a wall outlet. Instead, you are connecting your supply wires to the wires in the shop light, using the wire nuts we provide for your convenience.
Sunco’s LED Wraparound fixtures are direct wire shop lights.
Do you include daisy chain cables with your shop lights and do you sell them separately?
All of our shop lights are linkable and include cables to connect multiple lights together. At this time, we do not supply longer cables for daisy chain purposes or sell them separately.
Wraparound Shop Lights - included linking cables are 1.5" (short) and 8" (long).
Standard Shop Lights - include a 5' power cord that can be used for linking purposes.
Also, note that each shop light we sell will link with a select number of lights on the same power circuit. Due to varying power needs, refer to each product for the exact number of fixtures you can link.
How many LED Shop Lights can I link or daisy chain together?
Each Sunco LED Shop Light will link up to a certain number of lights on a single power source. Due to varying power needs, refer to each product for the exact number of fixtures you can link or the lists below.
All of our shop lights are linkable and include cables to connect multiple lights together. Wraparound LED Shop Lights each come with 2x linking cables, a short one for a seamless line of lights and a longer one to separate the fixtures. At this time, we do not supply very long cables for daisy chain purposes or sell them separately.
Wraparound Shop Light SIZE - LINK Chart:
- 5" - up to 8
- 7" - up to 6
- 8.5" - up to 5

How do PIR motion activated lights work?
Without going into the technical weeds of this topic, PIR or Passive Infrared technology includes an electronic sensor that detects motion by infrared (IR) objects or bodies within range of the sensor. That would include humans, dogs, and other animals, since we radiate heat. Note that the sensor detects a change in radiation levels, rather than looking at average IR levels.
When connected to an LED light bulb or LED tube light fixture, a PIR sensor detects a certain range of radiated heat or what is called infrared radiation. When the sensor detects a change in radiation within its tolerance levels, it will turn on the light. After motion stops, the light will turn itself off within a certain, set time period.
Sunco Motion Activated Shop Lights are designed to turn off after 10 minutes, when detected motion (radiation levels) stop. These lights are ideal for storage areas, basements, and infrequently used hallways, among other applications.
Also note that PIR motion activated LED bulbs should not be placed inside an enclosed fixture; it works best with open bulb design styles.
In addition, PIR sensors can be affected by extreme hot or cold weather. During intense heat, the sensor may not detect the moving heat signature from a passing person or animal due to the overall heat detected. During extreme cold weather, the sensor may be fooled into turning on with motion on a sunny day due to the variances between the cold surroundings and a passing person or animal.
If you are using these near sidewalks with frequent foot traffic, for example where a neighbor might walk a dog near your property, you can angle the light beam down and away from high traffic areas so that lights are not flashing on off unless needed on your property.
Other terms for this type of motion activation include: Pyroelectric and IR motion.
Can I use the plug on the side of your shop lights as an outlet?
No. The plug on Sunco LED Shop Lights is designed to be used only for daisy chain of our shop lights only. Do not use the plug as an outlet for appliances, vacuums, extension cables, etc. This will void your warranty.
Solar Lights
What are the best practices for Sunco Solar LED Lights?
Sunco solar lights are designed for outdoor gardens, yards, and pathways to provide landscape lighting without underground wiring. The integrated photocell sensor on our wet rated Solar LED will turn on the light when the sun sets and no light is detected.
Since the built in battery needs to be charged by the sun in order to light up at night, you will want to place our solar powered LED Path Lights and LED Garden Lights in full sunlight so they can charge for 6-8 hours. The solar lights will then provide 8-10 hours of bright light when it gets dark.
To help maintain your solar powered lights, please refrain from placing our path and garden solar lights under trees, shrubs, in the shade of tall walls or inside. Also, please be sure to avoid these low profile lights when mowing your lawn.
Sunco’s solar lights also perform best when placed away from streetlights. Otherwise, the streetlight might fool the sensor into thinking that it is daytime and it won’t turn on your light.
Tubes
My LED T8 Tubes won’t work. Can you help?
Yes, there are a number of troubleshooting things you can check to work through what might be the issue:
Ensure you bypass the ballast (or remove it) for optimal performance and energy savings. For safety reasons, a qualified electrician should perform any retrofitting.
An electrician can quickly cut the L/N wires from the ballast in your light fixture, cut the socket lead wires and connect the input wires to one end of the fixture in order to bypass the ballast. The LED T8 Tube will connect directly to the voltage line flowing into the sockets. The second tombstone acts as a stabilizer to hold the tube firmly in place (no electricity flows through that side).
Be sure your electrician attaches the label provided with our T8s to your retrofitted light fixture to ensure someone does not accidentally use a fluorescent linear tube instead of an appropriate LED tube after the ballast is removed. The label says: “Warning: Fixture has been modified. Ballast has been removed. Do NOT install fluorescent tubes. Use only 120/277V single-end LED tubes.” You can also notify your maintenance and office management personnel of this change.
The bi-pin end of your linear lamp tube (G13 in this case) is then secured on a tombstone in the slot between the metal contacts and conveniently placed plastic supports. This is the same for each type of socket.
Note that the grooves on the side of the socket are not just for decoration. The groves fit differently on separate lighting fixtures. Be sure to make note of where the grooves fit on your particular light fixture before beginning the retrofit process. These grooves are designed to slide your tombstone into the right position on the fixture.
Are you using non-shunted tombstones? Our LED T8 Tubes (SEP) require non-shunted tombstones. The electrical current flows through multiple tracks/paths in these sockets. Their contacts are not connected/joined.
That means that if you use our LED T8 Tubes with a shop light with a ballast and shunted tombstones, the tube may become unusable.
Check out our blog for more details on What Type of Socket You Need (Shunted vs. Non-Shunted Tombstones).
If neither of these solve your LED T8 Tube issues, please contact our Customer Service Specialists for assistance.
Do I want shunted or non-shunted tombstones for my LED T8 tubes?
You need non-shunted tombstones for our LED T8 tubes (SEP).
Check out our blog for more details on What Type of Socket You Need (Shunted vs. Non-Shunted Tombstones).
What are tombstones and why do I need non-shunted tombstones for an LED T8 Tube?
Our LED T8 tubes (SEP) pair with non-shunted tombstones. Tombstones are sockets used in a shop light to hold the light tube into place and direct the power. The electrical current flows through multiple tracks/paths in non-shunted sockets. Their contacts are not connected/joined.

Non-Shunted Tombstones
- Contacts are isolated (with 2 tracks for the electrical current to travel
- Single-sided / Single Ended Power (SEP)
- Bypass the ballast or remove the ballast
Shunted Tombstones
- Contacts join in one path
- Double-sided (DEP) – both ends of the tube are powered
- Ballast included
Check out our blog for more details on What Type of Socket You Need (Shunted vs. Non-Shunted Tombstones).
Are LED T8 Tubes ballast bypass compatible?
You need to bypass the ballast and use non-shunted tombstones for our Type B T8 LED Tubes to work properly.
Check out our blog for more details about removing the ballast and on What Type of Socket You Need (Shunted vs. Non-Shunted Tombstones). In a separate blog, you can learn more about the Advantages of Direct Wire T8 LED Tubes and how Type B T8 LEDs offer many benefits when compared to a fluorescent bulb.
What size are LED T8 Tubes? Do they fit in a T12 size fixture?
The same G13 bi-pin connector can be found on both T8 and T12 LED Tube lights. The T8 LED Tubes Sunco sells are approximately 1.12” in diameter. An average T12 is about 1.5” in diameter. The same connector means that you can theoretically use a T8 LED Tube to replace a fluorescent T12 tube light, as it should fit in the socket – and vice versa.
Also, be sure you use non-shunted tombstones and remove/bypass the ballast when using Sunco LED T8 Tubes. Need to know more about that? We got you covered. Check out our blog on What Type of Socket You Need (Shunted vs. Non-Shunted Tombstones).
Can I daisy chain your shop lights?
Yes, Sunco LED Shop Lights can be daisy chained together on the same power circuit. Please check our product pages to see how many shop lights can link together for each product type. The linkability counts are different.
For your convenience, we supply two connectors in the box with your shop light so you can daisy chain them together. One is small for a close or almost flush connection and the other provides a slightly wider spacing between the shop light fixtures in your light plan. We do not currently sell a longer extension cable for this purpose.
Also, please consult with a qualified professional electrician regarding your circuit capacities to ensure a daisy chain is suitable for your setup.
What does single-ended (SEP) and double-ended (DEP) mean regarding LED tubes?
Double-ended Power (DEP) tubes – the electricity flows through both sides of the tube. One is hot and one is neutral. Typically uses shunted tombstones.
Single-ended Power (SEP) tubes – hot and neutral are on one side of the tube. The non-shunted tombstones (sockets) used with this type will have power on one end. The second socket is used as a stabilizer to help secure the tube in place.
Want to know more? Visit our blog on What Type of Socket You Need (Shunted vs. Non-Shunted Tombstones).
Lighting Glossary
A
A-Series
The “A” in A-Series bulbs stands for arbitrary size.
This is the shape most people consider when thinking about a typical light bulb. They vary in size from the compact A15 for ceiling fans and refrigerator lights up to the A21, which offers a higher lumen count and also good heat dissipation.
Learn more about each bulb type in this Understanding Bulb Shapes blog.
Accent Light
Accent lights create mood and atmosphere in interior lighting. They do not provide the primary light in a room.
Accent lights are often decorative in nature yet can be functional, too. These lights can focus on artwork or an architectural element in a room or the style and design of an accent light can be a conversation starter.
In lighting design, accent lights are combined with ambient light and task light.
AFCI Breaker
Sunco LED Downlights and Slims are compatible with AFCI/Arc-Fault Circuit Breakers.
AFCI or AFI breakers detect parallel arcs. When/if an arc occurs between hot and neutral wires, the interrupter (breaker) will detect it and trip the breaker. It will also trip the breaker (de-energize the circuit) for anomalies that mimic arcing faults and downstream overloads.
This has been used in new residential homes since 2002.
Does not detect ground faults (See GFCI Breakers).
Afterglow
When a light bulb stays illuminated after the power is disengaged.
Afterglow happens when the LED driver stores electrical energy. The glowing can last from seconds to minutes. This sometimes happens with LEDs, but is more common with incandescent, fluorescent or other outdated lighting. With Sunco LEDs, this slight glow will not affect the quality or the lifetime of your bulb.
If you are seeing an afterglow, please confirm you are using a compatible dimmer switch by looking at our dimmer lists for each product under the Support tab for each product or by visiting the Manuals & Documentation page.
Alternating Current (AC)
Under an Alternating Current, the electric current reverses periodically to flow in two different directions. Voltage level also reverses. This contrasts with Direct Current (DC).
Residential homes are typically wired for AC.
Ambient Light
Although ambient light is typically natural lighting from the sun, when discussing interior lighting ambient light is often represented by ceiling or recessed lights, or large table/floor lamps to recreate bright, overall lighting that natural sunlight would create.
In interior lighting design, ambient light is combined with task light and accent light.
Amps/Ampere
Measurement of electrical current flowing past a given point in one second.
To calculate amps:
WATTS / VOLTS = AMPS
Anode
A positive electrode where oxidation occurs and the terminal where a current enters a polarized electrical device. It attracts electrons and can be a source of positive charge.
In a fluorescent tube, the Anode (+) sits at one end of the tube while the Cathode (-) is at the other end.
Another polarized electrical device is a battery.
ANSI / American National Standards Institute
A non-profit group that establishes voluntary consensus standards and conformity assessment systems. ANSI offers third-party product certifications and have open standards and essential requirements.
Area Light
Light fixtures that fill a broad space with a wide beam spread or beam angle.
Sunco offers several styles of area lights, including: LED Shoeboxes, UFO High Bay LED Light Fixtures, LED Flood Lights, and LED Wall Packs.
Atmosphere
The emotional feel of a space, usually subjective in nature. Atmosphere is created by the choice of lighting color temperatures, RGB color selection, light fixtures, and how dim or bright a light is in a room, among other things.
AWG / American Wire Gauge System
The North American standard for sizing electrical wires was set by the American Wire Gauge system (AWG) and has been in place since 1857. You may also see it referred to as Brown & Sharpe wire gauge. It is a logarithmic, stepped system to indicate the diameter sizing of electrically conducting wires (round/solid/nonferrous). AWG does not reflect the quality of a wire.
The AWG standard allows consumers to recognize that a set wire gauge (size) will be rated for a specific amount of amperes or amps. Smaller wires offer greater resistance than larger wires. For instance, a size 12 wire is rated for 20 amps. The current capacity of a wire indicates the amount of current that can be safely carried on that wire.
Wire Size & Amp Ratings for Copper AWG Wires
- 14 AWG – 15 amps
- 12 AWG – 20 amps
- 10 AWG – 30 amps
- 8 AWG – 40 amps
- 6 AWG – 55 amps
- 4 AWG – 70 amps
In the AWG designations, the larger number indicates a smaller wire size. The diameter of a 12-gauge wire would be larger than a 14-gauge wire.
Learn more about general wire sizing and gauges in our blog on How to Choose the Right Wire.
B
B-Series
The “B” in the B-series bulbs stands for blunt tip.
The Sunco B11 shape mimics a candle flame, but without a curve or wave at the tip.
Learn more about each bulb type in this Understanding Bulb Shapes blog.
Back Light
Lighting from behind an object.
This can be a light that provides a silhouette or outline of an item or person. This can also refer to a light fixture where the light comes from behind a panel.
Backplate
The rear mounting plate of a lighting fixture that attaches to a wall.
Sunco Wall Packs, Sconces, and Exit Signs include backplates.
Base
The bottom portion of a lightbulb. The base is where power is drawn from, and also how one secures a light bulb in a socket.
The base can be screw-in, twist and lock, bi-pin, bayonet, CFL, and other styles.
For more, see Bulb Base.
Baffle (Trim)
Baffle trim is used on our LED downlights. It features uniformed grooves close to the light source.
This trim minimizes glare to create a soft light. Softer light tends to be less straining on your eyes.
Ballast
Manages the distribution of energy in a fluorescent fixture to ensure necessary voltage, current, and waveform to start and operate the lamp. Ballasts are required for fluorescent and HID light sources to provide optimal circuit conditions. Without them, a fluorescent lamp would increase its current draw, overheat, and burn out.
When this type of fixture starts up, the ballast very briefly supplies a high voltage. This establishes an arc between the two lamp electrodes. With an established arc, the ballast reduces the voltage and regulates the current to produce a steady light output.
Electricity flows from the ballast through the tombstone/socket and into the lamp pins.
In fluorescent lights, before the lamp is turned on, tombstones provide power through the lamp’s cathodes. Unlike traditional fluorescent tubes, LED tubes include an internal driver. (Note that Sunco LED T8s are instant on and do not require power in advance of illumination.)
Ballasts can fail and are routinely replaced when they stop working. A failing ballast tends to blink rapidly or the light output of the fixture may be greatly diminished.
LED linear tubes like Sunco’s T8 LED Tubes bypass the ballast and use non-shunted tombstones. Learn more in our blog.
Ballast Bypass
Sunco T8 LED tubes are single-ended powered (SEP) linear tubes that do not require a ballast. They have an internal driver and are sometimes referred to as Type B. The LED tube connects directly to the voltage line that flows into the sockets.
The ballast is removed during installation of the LED tube while retrofitting an existing fluorescent light fixture to accept LED linear tubes.
Ballast bypass is also referred to as direct wire.
Ballast Compatible
No rewiring or ballast removal is required with this type of light. Features a fast install, LED replacement linear tube so you can upgrade existing fluorescent light fixtures.
Also known as plug-and-play or direct fit tubes.
Note that leaving a ballast in place, as opposed to Ballast Bypass, can result in added maintenance costs since the ballast tends to fail on a regular basis.
Beam Angle
The angle at which a light emits or distributes, measured at the point on both sides of the light spread where the intensity drops in half. Beam angles are shown in degrees and can affect the shape of the light produced.
The smaller the beam angle, the narrower the beam (often referred to as a spot).
The larger the beam angle, the wider the beam (flood).
More detailed information is available on our Lighting 101 page, along with a graphical representation of beam angles.
Beam Radius
Sometimes called light spread or beam width, the beam radius is a measurement of the circle or oval of light that appears on the floor.
Beam radius/light spread is typically measured in feet or meters. If you hang a light closer to the ground, then it will have a smaller beam radius.
Visit Lighting 101 to see a beam angle chart you can use as a reference.To create your own chart, follow this equation:
BEAM WIDTH = ANGLE x .018 x DISTANCE
Bi-Pin Base
This type of bulb base features two prongs or plugs at the end of the bulb. These plugs fit into compatible sockets to secure it in place and power the light bulb.
Electrical current flows through the pin base into the light bulb to generate light.
Some Sunco bi-pin bulbs and tubes include:
See Bulb Base for more details.
BR-Series
The “BR” in BR-Series Bulbs stands for bulged reflector.
These are directional flood lights with a wide beam spread for wall washing or to cast a wide pool of light in a room. Used mainly in recessed cans for downlights.
Learn more about each bulb type in this Understanding Bulb Shapes blog.
Brightness
The intensity a light bulb emits is measured in lumen count. Brightness is not measured with wattage. Check the lumens to determine brightness.
Most Sunco LED light bulbs are dimmable from 100% to 10% to reduce the brightness levels. Pair each bulb with a compatible dimmer. Dimmer lists for each light bulb are included in the Support tab.
You can dim our LED Smart Bulbs without a dimmer.
Bulb Base / Base Type
Used to secure a light bulb in place and also to provide power to the light bulb.
Bulbs come with a variety of bulb bases and sizes. Some are screw-in style like the standard A26 base or the candelabra E12. There are also 2-pin styles with a twist and lock GU24 or the dual pins on our LED replacement linear tubes.
Screw bases are powered by two soldered contact wires on the base. Pin bases include two pins or prongs to connect to voltage.
Base type is expressed as a letter or letters followed by a number (E26, G13, etc.).
Bulb Types
Bulb styles can vary greatly. Note that bulb type does not indicate the base.
“A” stands for arbitrary size. This is the shape most people consider when thinking about a typical light bulb. They vary in size from the compact A15 for ceiling fans and refrigerator lights up to the A21, which offers a higher lumen count and also good heat dissipation.
“B” in this series stands for blunt tip. The B11 shape mimics a candle flame, but without a curve or wave at the tip.
“BR” stands for bulged reflector. These are directional flood lights with a wide beam spread for wall washing or to cast a wide pool of light in a room. Used mainly in recessed cans for downlights.
“G” stands for globe. They work well in open fixtures where the globular shape is visible.
“PAR” stands for parabolic aluminized reflector. The reflector redirects downcast light in a highly directional beam. Great for spotlighting architectural elements, artwork, or as landscape lighting when wet rated.
“ST” stands for straight tubular. These bulbs are similar to the Edison clear glass bulbs from the early 1900s that had a filament inside. Except LED Filaments are brighter and more durable, yet still offer a nice amber glow.
“T” stands for tubular. These are long, narrow bulbs often used in pendants, open fixtures, or banker’s desk lamps.
Learn more about each bulb type in this Understanding Bulb Shapes blog.
C
Cable
A group of conductors (wires) enclosed in an insulated sheath or jacket. They may be twisted or parallel configuration.
CAFCI or CAFI Breaker
Detects parallel arcs + series arcs in wiring. When an arc occurs on a single wire, the interrupter (breaker) will detect the surge and trip the breaker. It can trip when the breaker carries 5A or more of load current and it detects a downstream arc or overload or short circuit.
Sunco LED Downlights and Slims are compatible with CAFCI (CAFI) Combination Arc-Fault Breakers.
Does not detect ground faults. See GFCI Breakers for more.
Can
A housing for recessed lighting that holds a lamp, bulb, or LED Retrofit. A recessed can usually includes a junction box.

Candela (cd)
Candela (cd) is a standard that has replaced the candle. A wax candle’s luminous intensity is roughly one candela.
People discussing lighting sometimes call candela candlepower.
In 1979, the General Conference on Weights and Measures (CGPM) adopted this definition of Candela: “The candela (cd) is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 × 1012 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian.”
In the International System of Units (SI), the Candela is a unit of measurement that involves human vision and the light we see emitted. Candela is not the entire amount of light emitted by an object, that refers to lumens. If you look at a laser pointer, it has a high candela (since all the light is pointed in a single direction) and a low lumen count.
In SI, the constant Kcd, is equal to 683 lumens per watt.
On May 20, 2019 the definition of Candela was refined to a more complex wording (which is why we included the original for clarity):
“The candela is defined by taking the fixed numerical value of the luminous efficacy of monochromatic radiation of frequency 540×1012 Hz, Kcd, to be 683 when expressed in the unit lm⋅W−1, which is equal to cd⋅sr⋅W−1, or cd⋅sr⋅kg−1⋅m−2⋅s3, where the kilogram, meter and second are defined in terms of h, c and Δνcs.”
Candelabra Bulb
A candle flame shaped light bulb that fits chandeliers, wall sconces, and sometimes string lights. Typically, a candelabra bulb features an E12 base.
Cathode
A negative electrode that accepts positively charged particles and the terminal where current exits or flows out. It is where reduction occurs.
Cathodes (-) are located at one end of a fluorescent tube while Anodes (+) are located on the opposite side. Another polarized electrical device is a battery.
Certifications
When a product is certified, it establishes that the product was tested within set standards or performance levels. Some certifications declare other things, such as the product does not contain harmful chemicals.
Most Sunco LED light bulbs and light fixtures are backed by certifications from organizations that approve or certify products for consumer safety. Our products feature many product certification programs, including Energy Star, UL Listed, FCC, ETL, DLC, CE, and RoHS.
Learn more about each organization on our helpful Certifications page.
Class 1 Circuit
A signaling system used to illuminate a light or signal equipment to turn on an audio signal, such as a bell or horn. Several Sunco lights use this to employ a Class 1 signaling circuit that illuminates the LED.
The National Electric Code (NEC) Article 725 designates Class 1, 2, 3 wiring details. A Class 1 circuit (signaling) can operate up to 600V. It is located in the wiring between the load side of a circuit breaker or fuse (an overcurrent device) and the connected equipment. It is installed in a conduit or protective cable assembly, such as a racetrack, for safety.
Class 1 circuits allow for more power than Class 2, which runs on low voltage. That means Class 1 circuits can accommodate more LEDs and are more effective than Class 1 drivers.
Class 2 Circuit
A low voltage circuit located between the load side of a Class 2 power source and the connected equipment. The power supply in this case would convert 120V power into low voltage.
The National Electric Code (NEC) Article 725 designates Class 1, 2, 3 wiring details. Class 2 wiring uses conductor sizes 18 AWG or 16 AWG. Class 2 provides acceptable protection from an electric shock and is considered to be safe from fire risk.
COB / Chip on Board
LED light bulbs with Chip on Board (COB) feature multiple LED chips (around 9 or more is typical). These chips are bonded directly to a substrate to form a single module.
COB LED lights efficiently produce single-color and do not create color changing bulbs or lights, due to its 2 contacts and 1 circuit. This style provides a bright, high lumen output with a minimum of 80 lumens per watt.
Color Rendering Index (CRI)
Indicates the level of accuracy an artificial light produces when compared to natural or sunlight quality light. Color Rendering Index is indicated with a scale of 0-100 and written like CRI 80 or CRI 90+.
In this scale, 100 is the closest to sunlight. The range of CRI 80-100 is considered to produce an accurate representation of an object’s color and texture.
Color Temperature
Absolute color temperature is measured in degrees of Kelvin (K) and represented as 2700K or 5000K, for example. The lower the temperature number, the warmer the light appearance. The higher the temperature number, the cooler the light appears.
Residential color temperatures typically fall between 2000K-6500K.
See more under Lighting 101.
Compact Fluorescent (CFL)
Compact Fluorescent (CFL) was designed to replace incandescent and halogen lamps as an energy-efficient alternative. CFLs feature either a twisted glass bulb style or a bent, small tube. The base of a CFL is either a screw-in or a plug-in style.
Compact Fluorescents are low power consumers, like fluorescent tubes, and sized to fit the same E26 socket as an A19 bulb. Some also contain an integrated ballast, like LEDs.
Although you can choose from a variety of color temperatures, CFLs color shift over time (unlike LEDs that produce same color temperature throughout the life of the bulb). CFLs include a warm-up period like fluorescent tubes of about 10-30 seconds.
While CFLs are a lower power consumer than those traditional bulbs mentioned above, LEDs are lower still in their power consumption.
Conductor
An insulated wire that carries electrical current.
Cones
Retinal photoreceptors that detect color. Rods can see black, white, and gray.
Cones require light to detect color. You experience this shift when viewing a dark room at dusk. It is hard to distinguish color at that time of day. You may see things in a gray scale in that scenario, instead of recognizing natural or accurate color.
Cool Light
In general, higher color temperatures deliver a cooler look.
Absolute color temperature is measured in degrees of Kelvin (K) on a scale from 1,000 to 10,000. This measurement allows you to describe the quality of a light. Typically, in commercial and residential lighting applications, Kelvin temperatures fall somewhere on a scale from 2000K to 6500K. When you want a specific look and feel in a room, choose the color temperature that best suits your project’s needs. The lower the temperature, the warmer the look; the higher the temperature, the cooler the look.
Cool color temperatures appear a the right of the Sunco Color Temperature chart shown in Lighting 101.
Sunco’s color temperatures include warmer colors under 3000K (Warm White), which appears yellow. Color tends to shift to cool when you reach 4000K (Cool White). The cool 6000K (Daylight Deluxe) appears silver in nature to our eyes.
If you want to learn more about this, you can see why you would choose a cool light by reviewing our blog on The Color of Light and CCT. There is a helpful chart showing Sunco color temperatures, the light appearance, and the ambiance or mood invoked by that color under the section called “Why Choose a Cool Light? (White, Blue, Silver)” near the end of the blog.
Another resource on this topic is the helpful chart and descriptions in our blog called Color Temperature Applications and Kelvin Levels Explained.
Current
An electrical current represents the rate an electric charge moves past a region or point. Current is not the distance charges move. Rather, it reflects how many charges pass that single point over time.
You can express this mathematically and calculate for it with this formula for current as a rate quantity:
CURRENT = I = Q/t
In this formula:
“I” refers to quantity current (expressed in amperes)
“Q” is the quantity of the charge passing through a point
“t” is the amount of time
Amperes (Amp or A) is the standard metric unit for a current.
1 Ampere = 1 coulomb / 1 second
The direction in which a positive charge (a mobile electron) would move is the direction of the current. When a switch is turned on for a light bulb, for instance, the circuit is closed. The electric field signal sends these electrons on the move. That movement happens immediately.
D
Daisy Chain
A daisy chain of lighting fixtures – through serial wiring – allows you to link multiple fixtures together on the same power source. Daisy chaining in a linear series allows you to turn on a select group of linked fixtures with the same light switch.
Select Sunco light fixtures are linked in a single circuit through plug and play capabilities, like most of our shop lights, wraparounds, and recessed lights.
To daisy-chain 4 linkable lights on the same circuit (instead of plugging the power cord into a wall or ceiling socket) connect the lights together so each light in the series is plugged into the previous one.
Be sure you check the technical specification on each product to note how many lights can safely be connected together as numbers vary.
For your convenience, linkable light fixtures include both a short connector and a longer connector to allow you to adjust the spacing between fixtures.
Damp Rated
A moisture rating. Damp rated light bulbs are intended for indoors or protected areas. They are intended for damp areas where water might condense, but not flow over the light fixture or bulb. An example might be a downlight or recessed can housing in a kitchen or bathroom.
In contrast, Wet Rated LED light bulbs and light fixtures are waterproof (IP65) and can be used in wet environments.
Learn more about it in our blog Choosing LED Damp vs. Wet Rated Lights. You may also be interested in our blog on Why IP Ratings are Important, where you can see a diagram of bathroom safety zones.
Daylight
The term “daylight” does not refer to whether a light bulb can be used outside or if a light bulb or fixture is wet rated. Sunco’s Daylight bulbs are 5000K color temperature, which is the closest color temperature to mimic natural sunlight (5000K-5600K).
Learn more about wet rating in our blog Choosing LED Damp vs. Wet Rated Lights.
Diffusion
A diffused light reduces glare and softens harsh light edges by spreading the light beam with an even concentration of light. Light fixtures diffuse light with frosted covers to adjust the light quality evenly across the beam.
Note that diffusion can create a wider source of scattered light. It also can affect light output, which is why frosted covers on one bulb type may have less lumens than their clear cover counterparts.
Dim / Dimmable
When you dim a light bulb, it changes in intensity.
Sunco offers dimmable LED light bulbs and retrofit LED downlights that adjust in a range from 100% brightness down to 10% when paired with a compatible dimmer.
NOTE: Sunco LED Smart Bulbs do not require a dimmer to adjust the light quality. Instead, use the dimming function on the app to make changes of this kind.
Dimmer (LED)
Lowers the brightness of a light bulb in a range of intensity levels. Dimmers are usually connected to wall light switches. LED dimmers send both power and control signals to the LED driver in an LED light bulb.
Dimming allows you to adjust the mood of a room by changing from bright light to a lower, darker level of brightness. Sunco dimmable LEDs lower in a range from 100% to 10% when paired with a compatible dimmer.
Please ensure that you use a compatible dimmer with Sunco light bulbs. Dimmer switches are tested for compatibility to grade lamp performance under various loads. Standard dimmers (not meant for LEDs) cannot provide the full brightness range and may also result in flickering or strobing effects. Mismatched dimmers can also result in a failed dimmer or LED driver. Sunco dimmer lists are available under the Support tab on each product page.
Also note: Sunco LED Smart Bulbs do not require a dimmer to adjust the light quality, just use the dimming function on the app to make changes of this kind.
DIP / Dual In-Line Package or DIPP / Dual In-Line Pin Package
Normally used on circuit boards, DIP or Dual In-Line Package features a rectangular housing. It has two parallel rows of electrical connecting pins beneath it. You can either through-hole mount these on printed circuit boards or insert into a socket.
Its design originated in an attempt to improve vibration resistance, provide good heat dissipation, and also include a hermetic seal against environmental intrusion and is an improvement upon the flatpack package. The standard format allows for in-field serviceability when it appeared in 1965.
An LED DIP chip typically produces around 4 lumens per LED, which is much less than newer chips offer. These were followed by SMD/SMT.
Direct Current (DC)
Electric current flows in one direction as a constant voltage or current. This is in contrast to Alternating Current (AC).
Batteries are DC.
Direct Wire
When you direct wire a light fixture (such as Sunco's Wraparound LED Shop Lights or LED Disk Downlights), you are not connecting a plug to a wall outlet. Instead, you connect supply wires to the wires in the light fixture. Wire nuts secure the connection quickly and are usually included with Sunco fixtures for your convenience.
This is sometimes referred to as hard wire.
Dirty Power
When power consistently fluctuates outside the acceptable range (usually 60Hz and +/-6V from 120V). You see this with flickering and blinking lights, breaker tripping, transformer issues, along with household equipment vibrations and noise. This issue is also referred to as surges, spikes, lags, dips, transients, or power interruptions. All of this disrupts technology’s functionality.
Dirty Power issues often appears in rural areas with inconsistent power or within older wiring.
Disk Downlight
Sunco LED Disk Downlights are circular and can be used either in a recessed can (with the included spring clips) or installed with a junction box in a direct wire, surface mounted technique (using holes in the rear of the unit that coordinate with different sized j-boxes).
Sunco’s LED Disk Downlight offers a streamlined look to your ceiling. It allows you to mount in existing or new recessed cans and can easily fit in a narrow ceiling by surface mounting to a junction box.
Downlight
Ceiling recessed lights that feature a low or small profile. The trim and the housing make up the major two components of this type of light. Sunco LED downlights also include clips to secure the fixture in place, along with a power input in the form of an E26 adapter and/or a TP24 connector.
Sunco LED downlights come in 4”, 5/6”, or 6” sizes and are compatible with our Recessed Cans.
Some downlights can surface mount (like the Sunco LED Disk Downlights or LED Slims). The rest require a recessed can and are called retrofit LED downlights.
You can learn more these two blogs on recessed lighting:
Drywall
A rigid finishing material to face interior walls or ceilings. It typically comes in rectangular sections and can be cut to fit. Also referenced as plasterboard, gypsum board, and wallboard.
Drywall panels are mostly gypsum (calcium sulfate dihydrate) with additives. Their surface is coated in paper that can be painted after a primer or wallpapered.
Drywall is usually added after the plumbing, electricity, and other internal wall or ceiling work has been completed. Sunco recessed lighting can be added to drywall ceilings before the drywall (New Construction Cans) or in a finished room (Remodel Cans).
G
G-Series
The “G” in G-Series stands for globe.
These bulbs work well in open fixtures where the globular shape is visible. They are typically seen lining vanity mirrors in home bathrooms or at salons.

P
PAR-Series
“PAR” stands for parabolic aluminized reflector in PAR-Series Bulbs. The reflector redirects downcast light in a highly directional beam. Great for spotlighting architectural elements, artwork, or as landscape lighting when wet rated.

More detail in Parabolic Aluminized Reflector (PAR).
S
ST-Series
“ST” stands for straight tubular in our ST Series Bulbs.
These bulbs are similar to the Edison clear glass bulbs from the early 1900s that featured a filament inside. LED Filaments are brighter and more durable, yet still offer a nice amber glow.

T
T-Series
The “T” in T-Series Bulbs stands for tubular. These are long, narrow bulbs often used in pendants, open fixtures, or banker’s desk lamps.
