Bright Tomorrow Lighting Prizes (or L-Prizes) will be awarded by DOE for solid state (LED) lighting developments that achieve targeted levels of energy efficiency and other traits. The Bright Tomorrow Lighting Prize competition, or "L Prize", was authorised by the Energy Independence and Security Act of 2007. It challenges the lighting industry to develop LED (light-emitting diode) replacement technologies for current widely used inefficient lighting products. The L Prize specifically seeks replacements for the 60-watt incandescent light bulb and the 4.75-inch-diameter halogen reflector lamp (technically referred to as a "PAR 38"). The replacement for the 60-watt bulb must result in 83% energy savings, using only 10 watts. The PAR 38 replacement is to use 15 watts; an energy savings of about 87%. Potential prize winners must also meet various technical requirements relating to the warmth of the light, the distribution of light from the lamp, the lamps dimensions, the product lifetime, and the companys ability to mass-produce the lamp. Also, a prize is established for a "Twenty-First Century Lamp" that achieves certain output, efficiency, and color targets - most notably the 21st Century Lamp will deliver more than 150 lm/W. This is much more than the 90 lm/W required for the 60-watt bulb replacement and the 123 lm/W required for the PAR 38 replacement. An added incentive provided for by the legislation, is that it calls for federal procurement of the winning LED lamps. After the awards are made, DOE is required to develop guidelines for federal agency purchases of the incandescent and halogen replacements, with the goal of complete replacement within five years. The lamps will also be promoted by the four major utilities in California, thanks to a Memorandum of Understanding between those utilities and DOE.

In August 2011, the DOE announced that Philips Lighting North America's highly efficient light emitting diode (LED) product won the first award in the 60-watt replacement bulb category. The winning product uses 10 Watts. In June, 2014 DOE suspended the remaining L-Prize competition for PAR38 bulbs. At the time, the market was not able to meet the competition's rigorous demands, and no further changes to the competition could be made.
