British Professor Colin Humphreys is working on a novel way to help ease the problem with a new form of lighting.

The Cambridge University scientist is making a material that he and others believe could help to cut emissions of carbon dioxide and other greenhouse gases by 15 per cent – by making low-voltage, longer-lasting and more efficient lightbulbs.

“At the moment the white LED is a harsh white -coaches and cars will soon have white LEDs inside but for homes it will not be very acceptable,” he said.

He estimates it could take about five to 10 years before the technology to produce gallium nitride LEDs with a more subtle white will be available but when this happens it could lead to real savings.
