LED Bulb Wins Energy Departments L Prize Competition
The U.S. Department of Energy announced that Philips has won the 60-watt replacement bulb category of the Bright Tomorrow Lighting Prize (L Prize) competition. The Department of Energy's L Prize challenged the lighting industry to develop high-performance, energy-saving replacements for conventional light bulbs that will save American consumers and businesses money. If every 60-watt incandescent bulb in the United States were replaced with the 10-watt L Prize winner, the nation would save about 35 terawatt-hours of electricity or $3.9 billion in one year and would avoid 20 million metric tons of carbon emissions.
Submitted in 2009, the Philips LED bulb successfully completed 18 months of demanding field, lab, and product testing to meet the rigorous requirements of the L Prize competition – ensuring that performance, quality, lifetime, cost and availability meet expectations for widespread adoption and mass manufacturing.
"The L Prize challenges the best and brightest minds in the U.S. lighting industry to make the technological leaps forward that can greatly reduce the money we spend to light our homes and businesses each year," said Energy Secretary Steven Chu. "Not only does the L Prize challenge innovative companies like Philips to make LED technology even more energy efficient, it also spurs the lighting industry to make LEDs affordable for American families."
"We looked at the L Prize challenge as an opportunity to innovate and develop an energy efficient alternative to a product that has remained largely unchanged for over a century," said Zia Eftekhar, CEO of Philips Lighting North America. "The fact that we are the first and only company capable of submitting a product and completing 18 months of rigorous testing not only underscores our commitment to innovation and quality, it highlights our ability to bring meaningful leading technologies into the mainstream."
Launched in 2008, the Energy Department's L Prize competition targets the 60-watt bulb because it is one of the most widely used types of light bulbs by consumers, representing roughly half of the domestic incandescent light bulb market.
The winning Philips product excelled through rigorous short-term and long-term performance testing carried out by independent laboratories and field assessments conducted with utilities and other partners. The product also performed well through a series of stress tests, in which the product was subjected to extreme conditions such as high and low temperatures, humidity, vibration, high and low voltage, and various electrical waveform distortions. The Philips L Prize winning product was also required to have a useful lifetime of more than 25,000 hours, compared with 1,000 to 3,000 hours for the products bulbs are intended to replace. The product uses solid-state lighting technology, which uses LEDs instead of electrical filaments, plasma or gas, and has the potential to use far less energy than other lighting technologies. As the winner, Philips will receive a $10 million cash prize as well as L Prize partner promotions and incentives. The L Prize-winning 60-watt equivalent LED bulb from Phillips could arrive in stores as soon as early 2012.
