The LivingColors Mini lamp contains 3 light emitting diodes (LEDs). 1 red, 1 blue and 1 green. Each one can be increased and reduced to achieve a total of 256 different colour combinations.
These mini lamps were £99.99 when they first came out. A friend of mine has one and i must say it does look VERY impressive in their living room at night.
Bargain at £49.99
