A lighting revolution is on the way that could end at the flick of a switch the battle between supporters of conventional bulbs and the eco-friendly variety.

Cambridge University researchers have developed cheap, light-emitting diode (LED) bulbs that produce brilliant light but use very little electricity. They will cost £2 and last up to 60 years.

Despite being smaller than a penny, they are 12 times more efficient than conventional tungsten bulbs and three times more efficient than the unpopular fluorescent low-energy versions.
