US 10 million lamp
Phillips Company has won U.S. $ 10 million of Bright Light Tomorrow Prize for its LED lamp (Light Emitting Diode) of 60 watts.
The prize was awarded by the US Department of Energy (DOE).
If all of 60-watt incandescent bulbs in the United States were replaced by this, the country would save about 35 terawatt hours of electricity or 3.9 billions in one year. The coolest thing is the economy of 20 million metric tons of carbon emissions!
The award has existed since 2008 and the lamp has gone through several rigorous tests, including extreme temperature changes, as well as tests of vibration, humidity, high and low voltage etc. The lamp lifetime is is 25,000 hours, while the common bulbs last between 1,000 and 3,000 hours.
The company says the lamp “could arrive in stores as soon as early 2012”.
