SINCELIGHT Dusk to Dawn LED Bulb with Dual Daylight Sensors· ON/Off Automatic Depends On Daylight Level · Night Light from Dusk Till Dawn · 9 Watt · 2 Pack [Energy Class E]

Very good quality,and great brightness from the bulbs,switch on and off as described,

Excellent condition bulbs that are bright and energy efficient. They activate by the amount of sunlight so literal come on at dusk and go out at dawn.much easier than a timer.👍😁

They work brilliantly

Bright, white light. They do turn on and off but struggle with dark, gray days in winter which is part of the British existence.

I love this product. I used one on the front and one on the back. Please turn on the light once, and that's it.This is great when you are not in the house. As soon as it gets dark, the light goes on. It's better than the timer, so you don't need to change it.In the morning, when it is daylight outside, the light turns off. So far, so good, and they have already been many months. I am unsure how long they last, but I will get more from you when they die.

Great, exactly what we were looking for either the right brightness

Why did you choose this product over others?:Have used other brands but they have all failed after a very short period. So far, these seem to be lasting

It works on 'open' spaces (where it is only minimally affected by its own light),but is unusable in enclosed, bright spaces:In our porch with white walls, the sensor gets 'crazy' from the reflection of the bulb's own lightand flickers for a long time during dusk and dawn.A delay between switching on and off and/ordifferent light thresholds between on and off could have solved this.Apparently not well thought through or tested.
