This is the gravity defying light bulb that floats in mid-air. A magnet inside the bulb is repelled by electromagnetic coils and magnets in its wood-look  base, a powerful opposing force that causes it to levitate and slowly spin. More than a novelty, four ribbon LEDs inside the shatterproof bulb produce a warm yellow glow like a vintage incandescent bulb. Simply touching the base turns the bulb on and off, and it hovers continuously as long as the base is powered. Base plugs into AC. Bulb: 5 1/2" H x 3" Diam.; Base: 1" H x 4 3/4" W x 4 3/4" D. (1 1/2 lbs.)
