These lights are so cool! The shades are Enameled steel, and do suffer from damage done to them over the years. Electricity would have been provided to the two insulators mounted on either side of the shade, and the shades are 21″ wide by 15″ tall. Light sockets currently do not work, and have an extremely oddball bulb socket. The brackets are galvanized steel, extend out 5 feet, and the bracket is 27″ tall at the back end. Please, no painting on these! Two available, prop rental only.
