A new way of making LEDs could see household lighting bills reduced by up to 75% in five years time, thanks to research at Cambridge University. The new LEDs use Gallium Nitride (GaN), a man-made semiconductor that emits a brilliant bright light but uses very little electricity. Until now high production costs have made GaN lighting too expensive for widespread use in homes and offices. The Cambridge University Centre for Gallium Nitride, got funding from the Engineering and Physical Sciences. (source: admin.cam.ac.uk)
