L Prize Competition Overview
The Energy Independence and Security Act of 2007 directed the U.S. Department of Energy (DOE) to establish the Bright Tomorrow Lighting Prize (L Prize) competition. The L Prize competition is the first government-sponsored technology competition designed to spur development of ultra-efficient solid-state lighting products to replace common lighting products.
The legislation challenged industry to develop replacement technologies for two of today's most widely used and inefficient technologies: 60W incandescent lamps and PAR38 halogen lamps. It also called for development of a 21st Century Lamp that delivers more than 150 lm/W.
The L Prize for the 60W incandescent replacement category was awarded in August 2011, including a US$10 million cash prize. That category has since been closed.
In 2014, DOE suspended the L Prize PAR38 competition. The competition set reach targets for industry, and current LED PAR38 products on the market fall far short of reaching the rigorous L Prize targets. No entries were received, and this category of the competition was closed.
The complete competition requirements for the 21st Century category have not yet been fully defined or published, and the category is not open for entries at this time.
