The new L-Prize® competition, launched in 2021, is designed to catalyze transformative LED lighting innovation, products, and impact. The L-Prize is primed to unlock the full potential of LED technology—to combine high luminaire efficacy with exceptional lighting quality, data-driven control and functionality, and sustainable design and construction for the future of illumination in commercial buildings. In addition to these technical innovations, the L-Prize also prioritizes diversity, equity, and inclusion in how luminaires or lighting systems can benefit communities that have been historically disadvantaged.

60W L-Prize Competition

The first L-Prize, awarded in 2011, recognized breakthrough performance in an LED replacement for the common 60-watt light bulb. The technology innovations in the winning product—including more efficacious LED chips, electronic miniaturization, better heat transfer, improved optics, and remote phosphors—have had a lasting impact, finding their way into millions of subsequent products that continue to save massive amounts of energy each year.
