This giant rotating light turns your room into a disco, with bright ever-moving multicolor circles projected all over your walls, ceiling, and floor as the ball spins. Can be set on a table or hung sideways on a wall. The ball measures an impressive 11" diameter, and the entire item (including the base) is 11" wide by 15" height. Plugs into any standard 110v outlet. Bulb is included and can be easily replaced with a 60w light bulb.
