The bulb is truly as bright as it claims - The sensor really understands day and night and is perfectly consistent - The name Osram does the rest. I give it 5 stars because I expect it to withstand the test of time (if not, I will reconsider).

The light darkens, the lamp turns on, it dawns, the lamp turns off. The light sensor is very useful! and effective! they have been working perfectly for a week.

Although a bit more expensive than other lamps with light sensor, I hope they work properly too... Some other brands I had bought broke in 10 and 20 days...

I will definitely write again after 2-3 months

7 months later, the lamps are excellent!
Most importantly, they have not broken down like many other brands I have bought, cheaper of course.
They do their job perfectly!
