A Brighter Tomorrow

An answer to our energy future that’s here today.

About the L Prize

The L Prize is the first government-sponsored technology competition challenging lighting manufacturers to push the limits of energy efficiency and develop a high quality solid state lighting product to replace the common incandescent bulb.




Spurred by the Energy Independence and Security Act (EISA) of 2007, the U.S. Department of Energy (DOE) established the L Prize competition to replace today’s most widely used and inefficient technologies – the 60W incandescent bulb and the PAR38 halogen bulb. The competition requirements complied with those outlined in the legislation, and included a rigorous evaluation process for performance which included testing conducted by independent laboratories and field assessments in collaboration with utilities and other partners, ensuring the performance, quality and energy efficiency of the winning product.

Creating meaningful solutions. LED lighting is changing the world, and Philips is driving the switch to energy-efficient solutions, and shaping the future with exciting new lighting technologies.  When the competition was first announced in 2008, we immediately went to work.  As a global leader in lighting and LEDs, we invest deeply in its future through research and product solutions. It requires market leading expertise in LED technology, and an understanding of the complexities and challenges critical to the development of effective LED lighting – from chips and optics to thermal control and lamp design. But it’s even more than a mastery of technology – it’s knowing what people need too. We call it meaningful innovation, and the Philips Award Winning LED Bulb reflects this commitment.




Philips has been awarded the prize because of the energy and environmental savings it delivers, but this is one case where everyone wins. Philips Award Winning LED Bulb represents a major technological leap forward for LED replacement lamps. That means, if every socket in the U.S. converted their 60W incandescent lamps to this new 10W L Prize lamp, the country could save approximately 35 terawatt-hours of electricity in one year, and avoid 20 million metric tons of carbon emissions. That’s enough electricity to power the lights of nearly 18 million U.S. households, or nearly triple the annual electricity consumption of the city of Washington D.C.
