Buy-NowSq2xOpen Up Lamp

A lamp shade that opens and closes when the light is switched on and off.

The lampshade is comprised of polypropylene “petals” and six bi-metallic strips which are activated by the heat emitted by a bulb. Bi-metallic strips are a sandwich of copper and steel. When heated, the copper expands more than the steel causing the strip to bend.
