These wonderful lamps with their amazing 3-D holographic windows use 16 LEDs bound to a rotating spindle to display a mass of stars or exploding starbursts swirling around inside them - either in warm white or rainbow colours. These come in two sizes, 60cm and 45cm, and are housed in a highly polished stainless steel frame. The Pyramids are for indoor use only and are supplied with a low voltage mains transformer.
