This custom built cast brass pendant light is 18 inches tall (not counting the chain) and the green and white porcelain cover is 18 inches wide. It comes with 3 feet of chain, but more can be ordered if needed. To access the bulb, the cage and globe thread off as one piece. The green and white porcelain cover is held in place by the cage threaded back in place. The porcelain cover will have some chipping like the photos show.
