The L Prize competition spurs the development of new, ultra-efficient lighting products to replace common light sources, including the 60-watt (W) incandescent bulb and the PAR38 reflector bulb. The goal is to realize significant lighting energy savings through widespread product adoption. Winning manufacturers receive significant recognition, and retailers, energy efficiency programs, and consumers benefit from energy savings and excellent lighting quality. The L Prize contributes to the goal of reducing building energy use by 50% and building energy costs by $2.2 trillion by 2030 by enabling products that use 80% less energy to provide the same amount of light as the incumbent technology.
