The Energy Independence and Security Act of 2007 directed the United States Department of Energy to establish the L-Prize competition, designed to spur development of LED replacements for 60W incandescent lamps and PAR38 halogen lamps as well as an ultra-efficient 21st Century Lamp. The original L-Prize Competition, launched in 2008, focused on an LED replacement for the common 60-watt light bulb and this L-Prize was awarded in 2011. The PAR38 competition was launched but received no entries and was suspended in 2014. The 21st Century Lamp competition was never opened.
