The light sensor reacts as already mentioned very sensitive to the ambient brightness. Once it is dim, the LED wall light turns on and stays weak. As it gets darker the room, the light from the LED light will automatically light. The maximum brightness is sufficient to orient themselves safely in a completely darkened room.
The sensor reacts very fast. If one turns the light in the room, the LED wall light goes off immediately and reversed again. It works amazingly well.
Practically on the LED wall lamp is the rotatable cap, with which you can influence the direction to which the light appears. One can therefore judge the light cone on the floor, the wall or elsewhere through, depending on how you want it to.
Since the LED wall lamp consumes only 0.5 watt and turns off automatically when it is in the room bright enough, you can always let them confidently in the socket. We both have children and the hall to the bathroom with it and are completely satisfied.
