This is what they use on the Michael Jackson’s Billie Jean video clip when he flip the coin to the beggar’s cup. This is the Airswitch Lamp, air switch means you don’t have to touch the lamp to switch on the light. Just move your hand horizontally above the lamp to turn on or off while raising your hand vertically or moving your hand down will dim the light. The Airswitch Lamp is available for $79.
