LED light bulb only for $2.80 lasts up to 60 years
Is it a lighting revolution on the way?Thanks to a British professor’s newest tech, a new eco-friendly solution that last up to 60 years could replace conventional and any other low-energy versions bulbs
Cambridge University researchers have developed cheap, light-emitting diode (LED) bulbs that produce brilliant light but use very little electricity.
They will cost just GBP2 (USD2.80) and last up to 60 years. The gallium nitride based bulbs are 12 times more efficient than conventional tungsten incandescent bulbs and three times more efficient than compact fluorescent low-energy bulbs. As well as lasting 100,000 hours, ten times as long as today’s eco-bulbs, the LED bulbs do not contain mercury, so disposal is less damaging to the environment, they do not flicker and fully illuminate instantly, unlike the current generation of eco-bulbs…READ MORE
