A prize-winning light bulb that lasts for 20 years is going on sale in the US on Sunday – also known as Earth Day.
Using LEDs endows the light with a long life and a hefty price tag. The first versions are set to cost $60
Philips has arranged discounts with shops that will sell the bulb meaning some could buy it for only $20
The bulb triumphed in the Bright Tomorrow competition run by the US Department of Energy that aimed to find an energy efficient alternative to the 60-watt incandescent light bulb.
The DoE challenged firms to develop a design that gave out a warm light similar to that from an incandescent bulbs but was much more energy efficient.
Philips was the only entrant for the competition and its design underwent 18 months of testing before being declared a winner.

“Because the new bulb is 83 percent more energy efficient than the standard 60-watt incandescent, consumers can now experience new savings for their pocketbooks,” Philips’ North America executive Ed Crawford said in announcing rebates.
International Earth Day, now in its 42nd year, was celebrated by environmentalists Sunday seeking to bring attention to climate change and pollution, and highlight ways to save energy.
President Barack Obama issued a US proclamation for the day to “reflect on the challenges that remain,” and confront the “most urgent environmental issues and rallied around a single message: the success of future generations depends upon how we act today.”
