The new LEDs use Gallium Nitride (GaN), a man-made semiconductor that emits a brilliant bright light but uses very little electricity.
GaN LEDs do not contain mercury eliminating the environmental problems posed by their disposal.
GaN LEDs also have the advantage of turning on instantly and being dimmable.
Only needs replacing after 60 years!
Professor Colin Humphreys, lead scientist on the project from Cambridge University-based Centre for Gallium Nitride our future will be bright and safe!
