The U.S. Department of Energy (DOE) has announced plans to modify the competition requirements for the L Prize's PAR 38 category. On Jan. 5, the DOE temporarily suspended the PAR 38 portion of the competition, and entries will not be accepted until that category reopens in May. The 60W replacement-lamp competition category will remain open during this period.

The DOE decided to close the PAR 38 category so that it could make modifications based on lessons learned from the 60W replacement competition. The legislated technical requirements for the PAR 38 competition will remain unchanged, and the DOE plans to announce and publish the revised PAR 38 requirements at Lightfair in May.

The L Prize is sponsored by the DOE and is the first government-sponsored technology competition designed to encourage lighting manufacturers to develop high-quality, high-efficiency solid-state lighting products to replace the common incandescent light bulb. The competition was originally announced and outlined in the Energy Independence and Security Act of 2007.
