Hi, thanks for your response. The issue is that I want the motion sensor to be activated only at night so I connect it to a photo cell that shares it with two low-consumption lamps. So far I tried it and it works perfect. What I don't want is that I burned the LED reflector. In my father's house the Led reflector was as if blinking and does not turn on after a few months
Just for that they come integrated with photocell, to have the option that only works at night. It is usually adjustable through a preset identified with a sun and a moon. Adjust the preset closer to the moon and it will work only at night (you regulate it until you find the point), in that case the external photocell would be too much but if it works leave it as is
regards
