Review on AmeriTop Dusk To Dawn Light Bulb- 2 Pack, A19 LED Sensor Light Bulbs; UL Listed, Automatic On/Off, 800 Lumen, 10W(60 Watt Equivalent), E26 Base, Indoor/Outdoor Lighting Bulb (5000K Daylight) by Robert Dickinson

Tried several GE dusk to dawn bulbs but after initial success developed numerous problems with them not coming on at dusk, or coming on and shutting off a couple hours later, while still in total darkness. Tried all the trouble-shooting methods, but the GEs still weren't reliable. so ordered two boxes of the AmeriTop A19 LED Sensor Light Bulbs, two bulbs each.These work. every time. exactly as claimed. I bought the 800 lumen, 5000K Day Light (bright white, not the warm, yellow) version. Unfortunately, while I have a lux meter I didn't think to test the bulbs prior to installation. After the installation I'd estimate they are a 60-80 watt equivalent replacement. These10 watt LED bulbs actually throw a lot of light, a bit more than my malfunctioning GE dusk to dawns, and are rated for 15,000 hours, meaning they should last around 3.4 years presuming 12 hours of illumination per day.These are a very reliable automatic dusk to dawn LED bulb. I highly recommend.
