DOE announced on August 3 that Philips Lighting North America won the 60-watt replacement bulb category of the Bright Tomorrow Lighting Prize (L Prize) competition. As the winner, Philips will receive a $10 million cash prize as well as L Prize partner promotions and incentives. DOE's L Prize competition challenged the lighting industry to develop high-performance, energy-saving replacements for conventional lightbulbs.

Submitted in 2009, the Philips LED bulb successfully completed 18 months of intensive 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. If every 60-watt incandescent bulb in the United States were replaced with the 10-watt L Prize winner, the nation would save $3.9 billion in one year and would avoid 20 million metric tons of carbon emissions.

Launched in 2008, DOE's L Prize competition targets the 60-watt bulb because it is one of the most widely used types of lightbulbs by consumers, representing roughly half of the domestic incandescent lightbulb market. See the DOE press release and the L Prize website.
