L-Prize; Bright Tomorrow Lighting Prizes

PAR38 Replacement Competition

Effective June 13, 2014, the U.S. Department of Energy (DOE) has suspended the L Prize PAR38 Competition, and no entries will be accepted at this time. The competition sets reach targets for industry, and current LED PAR38 products on the market fall far short of reaching the rigorous L Prize targets, making it unlikely DOE will receive a qualifying entry in a reasonable amount of time. DOE cannot lower the efficacy target because it was set by Congress. DOE will continue to monitor the PAR38 market for performance and price improvements, to consider reopening the competition at a later date.

The PAR38 competition requirements call for exceptional performance by LED products that can meet the most demanding applications for reflector lamp beam performance, color quality, and energy efficiency. Products capable of meeting these specifications will be appropriate for retail displays, museums and galleries, hotel lobbies, and other settings requiring high-intensity spot lighting with excellent color rendering, while slashing energy use by 85% and lasting 10 times longer than halogen lamps.

Competition Requirements

The PAR38 competition requirements have been revised as of July 2013. The updated requirements include the same performance specifications detailed in the EISA legislation that established the competition. Key changes in the July revision focus on:

  • Revision to allowable beam angle
  • Dropped requirement for production of specific number of units
  • Revision to domestic content requirements

The new competition requirements supersede the revised competition requirements issued in 2012.
