The back of the fixture is 4 1/2 inches. They were tested and both work.
They take regular sized light bulbs. They are approximately 12" wide 8" tall (not including a bulb).
They are very pretty, and would look nice in a traditional setting, as well as a room with a lot of grays or neutrals, because they are just simply clear and silver and quite sparkly. I hope you will enjoy them!The item "PAIR Vintage Crystal Chandelier Wall Sconces With 2 arms 12 Prisms each fixture" is in sale since Thursday, January 24, 2019.
