My conclusion after 4 weeks: The light with its 2 LEDs is really very bright. The spotlight is on the floor and lit the way out; Here you have the keys so that you do not hide themselves and the neighbors still mitausleuchtet. There are - as already mentioned - no on / off switch. To replace the batteries of these would possibly be helpful; otherwise it is not necessary. After all, is to be turned on with every movement of the spotlight. This is excellent at dusk.
