The lamp consists of three small light-shades covering three halogen bulbs, all surrounded by a fourth, larger shade.
The shades are made of a transparent, reflective material and are shaped like propellers. As the heat emitted by the bulbs rises, the four shades rotate.
The following information is from Bertjan Pot:
The revolving chandelier
The revolving chandelier has four, half reflective, half transparent light-shades. The lightshades are shaped like a propellor and balance on a small steel tip. The rising air, heated by the three halogen bulbs makes all four lightshades rotate.
The idea of heat making a lightshade rotate is nothing new of course... many of you probably had a bed light when you were young with a small rotating landscape scene.
One day in the near future halogen lights will probably be banned. I still don’t know if this is good or bad. Up untill now there still is no good energy efficient full-spectrum replacement for the halogen bulbs. In the case of the revolving chandelier, at least the excess energy (heat in stead of light) is used to do something extra for the light... making it revolve silently and make the whole light twinkle like an old-fashioned chandelier.
For now the revolving chandelier is produced in a limited edition of 12.
It will be shown at the wonderful shop of Rossana Orlandi in Milan, during the Salone 2009.
