    Terrific Product

    Ordering was simple and delivery was prompt. The product was well packed so no breakage occurred. The choice of light intensity is a nice feature when shopping. The bulbs themselve are tific. They have grat "curb appeal" and put out some seious lumens for my security cameeras.

    ST64 LED Bulb Working Better Than Expected

    Using outdoors in a post lamp and lamp fixtures across the front of the house. The lamps do not interfere with each other (dusk to dawn sensors). And so far, they also operate at below zero temperatures.

    I’ve purchased these same bulbs before. They turn on and off perfectly. A little disappointed they only lasted 2 years.
