This is a great set of lamps. The three motion lamps are great for stairs or dark closets or basement areas. The range is about 5-6 feet to trigger the light. Comes with batteries and adhesive to mount to wall or stairs. Touch lamp is good as well. Good for coat closets or spaces you want light up better when needed. The batteries last about a month in semi well travelled areas. Will last longer in less travelled areas and shorter in heavy areas.
