DOE Releases Revised L Prize Competition Requirements
July 26, 2009
The U.S. Department of Energy has released revised competition requirements for the L Prize, the first government-sponsored technology competition designed to accelerate development of high-quality, high-efficiency solid-state lighting (SSL) products to replace the common light bulb.
The revised competition requirements include updates in three key areas:
Revision to the eligibility requirements. As a result of industry/stakeholder feedback, current state-of-the-art of SSL technology, and lessons learned through practice of SSL products, the eligibility requirements for the competition have been revised. The change reflects current approaches available on the market and allows for greater participation in the L Prize competition.
Revision to correlated color temperature (CCT). In order to maintain the competition's intent for high quality light, the CCT specification has been complimented with a specification for chromaticity.
Revision to the PAR 38 minimum center beam candle power (CBCP). Based on additional analysis of baseline technologies and benchmark testing through the DOE CALiPER program, the minimum CBCP specification has been revised for the PAR 38 category in order to more accurately reflect the products the L Prize is intended to replace.
