The city of London is set to receive a £2.4 million traffic light upgrade that will replace 3,500 existing lamps at some 300 junctions with energy-efficient light-emitting diodes (LEDs). Compared to standard lights, LEDs consume 60 per cent less electricity and thus generate far less carbon dioxide emissions.

Researchers at the University of Cambridge say they have developed a new type of LED light bulb that could slash electricity consumption and burn for 100,000 hours , which would translate into about 60 years’ worth of typical household use. The LED uses gallium nitride, which generates bright, energy-efficient lighting
