The wall lights can be used variably: Staircase lighting, cabinet interior lighting or night light for a hallway or bathroom. The light is slightly cool, ranging from the brightness of, to put a few square meters in pleasant twilight before it for a good thirty seconds expires independently again.
The battery or battery change is possible without tools, the tray can be screwed easily with the thumb nail. Installed is the light through a thin plate that is either bolted or secured with double sided tape. That would be my only complaint: a simple hole for hanging on a nail would be helpful.
