DOE Launches Next Phase of Competition to Create Efficient Lighting

March 14, 2012

DOE on March 8 launched the next phase of the Bright Tomorrow Lighting Prize (L Prize) competition, which challenges the lighting industry to develop high-performance, energy-saving replacements for conventional light bulbs. The latest competition will spur leading-edge companies to build innovative LED replacements for conventional parabolic aluminized reflector (PAR 38) lamps, commonly known as spot or flood lamps.

Approximately 90 million PAR 38 light bulbs are installed in the United States, and DOE estimates that replacing them with bulbs efficient enough to win the L Prize would save the country 11 terawatt-hours of electricity per year, approximately as much electricity Washington, D.C., consumes each year. The rigorous performance testing needed to win the L Prize ensures that the performance, quality, lifetime, costs, and availability of winning products meet expectations for mass manufacturing and widespread adoption. For the PAR 38 category, at least 50% of the LEDs must be produced in the United States, and all of the assembly must be done here. See the DOE press release and the L Prize website.
