I tested it and it works but would recommend having it rewired. There is some color loss on them as well as cracks at the tops of the balls or spheres.
Each light measure roughly 7-8 in diameter (forgot to measure before I packed). Keep in mind these atomic looking lamps are very old. Very very cool and deserve to be saved.
