Ideal for illuminating paintings, wall-hangings or bookcases that lack a nearby power source, this polished brass lamp attaches to any frame or wall and operates without a power cord. The lampshade¿s highly reflective interior emphasizes the generous glow of a standard #31 light bulb (included), and projects glare-free light evenly across a 16- by 20-inch painting. Adjusting between five and seven inches in length, the lamp arm has three independent joints to achieve the best possible angle and light proximity to a painting. Four AA batteries (included) provide the lamp with six to eight hours of illumination, and the unit comes with hanging hardware. 1 3/4" H x 7" W. (2 lbs.)
