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!
