In Wireless luminaires are operated with 3 AA batteries. In the package are the same tape with which you can attach the lamp well in the closet. The motion, or rather light detector reacts well but you have only hand toward lamp routes so that these concerns. That would be the case if you are looking for something in the closet and into the hand moves. Compared to some other type of light with motion detector reacts as described this very sluggish. The Helleigkeit is very good. The burn time is sufficient. Only there are no long-term experience with the life of the batteries.
