Cleverly designed to look like mortise and tenon joinery, this cherry finish night light with MDF core, is light sensitive, so you never have to remember to turn it on or off. This product is adapted from the circular glass dome, designed by Wright in 1943 for the S. C. Johnson Administration Building and is visible there today. The original is a complex series of ever-enlarging circles comprised of glass tube, reinforced by a pattern of circular steel bands. 4"x6"x1.5". Made in the USA.
