From the company that brought you the Lava Lamp in the 1960s, the Airswitch® 1 (2004) operates without the user ever touching the lamp. Like its name says, the “switch” is in the air. Simply move your hand over the top of the flask to turn it on and off. Raise and lower your hand to adjust the light from very dim to bright enough for reading. These instructions, should you forget them, appear as an iconographic display on the flask (printed on only one side, giving you the option of keeping this information visible or turned from view). Bulb (included): E17/110V/40W pearlescent candle.
