Delivery details


The Open Up Lamp is an ingenious lampshade that opens up when the light is turned on, and closes up when it is switched off. Create a warm glow with the Open Up Lamp, designed exclusively by the Science Museum's Inventor-in-Residence Mark Champkins! The lampshade is made up 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.

The effect is a beautiful flower-like lampshade, which with a 90W energy saving bulb will open to its fullest extent in five minutes. Easily connect the pieces together and switch on to enjoy the gentle glow.

The Open Up Lamp box contains six polypropylene "petals" (three inner petals with pointed ends and three outer petals with rounded ends), one steel clamp and six bi-metallic strips.

Please note, the metal elements of the lamp get very hot; do not touch them whilst the light is on, or for ten minutes after the light is turned off.

"It's a great design because is simple and beautifull and it's easy to asemble too. But we have had problems with the diameter of the lampholder."

Excellent family lamp

"This is a fantastic product, which is loved by the whole family. Adults love it for its simple/modern design, whilst children are excited by the way it opens up. Word of warning, energy saving bulbs do not produce enough heat, but other bulbs are easily and cheaply available."
