LED will replace household light bulbs in 3 years

Researchers have made LED lightbulbs that are brighter and use less power than both standard light bulbs and energy efficient light bulbs, using nano imprint lithography to make microscopic holes on the surface of the LEDs so that more light escapes. With
current LEDs, much of the light is trapped within the LED's structure.

Dr Faiz Rahman, the researcher leading the project at the University of Glasgow, said: “LEDs not only use less power than current energy efficient light-bulbs but they are much smaller and can last years without needing to be replaced. This means the days of the humble light-bulb could soon be over.”
