SINCELIGHT Dusk to Dawn LED Light Bulb 9W with Dual Photocell Sensors, ON/Off Automatic Depends on the Daylight Level, Outdoor Night Light from Dusk Till Dawn, Security Bulbs, Warm White 3000K, 2 Pack

first class work as they say exhalent

Nice quality and perfectly glowing

The lightbulbs are good in every respect except that they come on quite early before dusk actually falls. I suppose it’s something to do with the sensitivity of the light sensors. Other than that they are a good price, very bright and I’m very satisfied.

Perfect. We use these in my outside light. Glad to get replacements

I am currently working my way through different manufacturers daylight sensing/dawn to dusk bulbs. All arrive in impressive packaging, and neatly turned out. All work straight away, and one or two have exceeded 6 months. As the majority claim an expected life of 25.000 hours something is going wrong. I have many ordinary LED bulbs in the house, and their life is impressive. I like them. My feeling is that sensing bulbs can be let down by the sensor failing. Do I have scientific evidence? No, just observing how these bulbs last in normal conditions over measured periods. As for this bulb. I give it full marks after its first week. I am pleased with it, and if it slogs through 25,000 hours of life I will tell you. Just make sure that if you buy one check out its life span.

Excellent

Mine lasted 3 years before it needed replacing, which is pretty good considering it was out in all weathers. It just started flashing one night so I replaced it. Great for carriage lamps when you don't want to have to turn them on and off manually. They are quite bright though, I would have preferred it to have been a bit darker for overnight.

Prob good for outside use as learned after receiving it. Not for inside use as its activated not by darkness or daylight but only when its sunny . And we ain't had any sunlight since last year. I must find out now how to return them.
