The CALABI-YAU lighting system is a self assembly lighting system, made up of interlocking quadrilaterals. Lamp shades of various sizes can be constructed by linking together the identical modules, allowing the end user to build the classical sphere. The standard CALABI-YAU lighting system pack contains 30 modules.
The standard pack is available in 5 sizes (55cm, 45cm, 35cm, 25cm and 17cm), all containing 30 modules, including an electrical cable and an energy saving lamp.
