Current L-Prize Competition
Concept Phase
The L-Prize Concept Phase invited innovative concept proposals documenting a luminaire and lighting system of the future. The Concept Phase completed in February 2022, with four winners announced by Energy Secretary Jennifer Granholm: * Project Tango, submitted by QuarkStar of Las Vegas, Nevada. The networked, white-tunable luminaire concept leverages innovations in optics, LED, and power conversion technology to deliver high efficacy, exceptional quality of light, and precise control of light distribution. * Sustainable and Connected Troffer Retrofit, submitted by Orion Energy Systems of Jacksonville, Florida. The concept offers a high-efficacy, networked LED luminaire with advanced controls that can be retrofitted in less than two minutes to an existing fluorescent luminaire. * Laterally Symmetrical Level 3 Engine for 3D Printing, submitted by Smash the Bulb/Bridgelux of Mountain View, California. This 3D-printed semi-indirect luminaire concept uses a high-performance light engine that requires no secondary optics and delivers high efficacy and excellent quality of light; an innovative optical design that reduces losses and addresses glare; and a luminaire housing that can be 3D printed on the job site. * Papaya Modular Lighting Ecosystem, submitted by Papaya of Evanston, Illinois. This highly modular luminaire platform designed by a team from outside the lighting industry uses a unique community-based approach; an all open-source aspect offers opportunities for innovators of all types to participate in evolving and innovating this lighting solution over time.Prototype Phase
The L-Prize Prototype Phase began on June 30, 2022, and seeks physical prototype systems, emphasizing technological innovation and challenging competitors to think outside the standard forms, materials, and price points of commercially available products. Up to six competitors earning the most points for innovations exceeding minimum performance requirements will share an award of $2 million. The Prototype Phase features two separate tracks: a luminaire track and a connected systems track and competitors may submit an entry for one track or separate entries for both tracks. DOE rules state that each track’s submissions will be judged independently. The Prototype Phase also initiated a teaming-opportunities process for the future Manufacturing and Installation Phase.Manufacturing and Installation Phase
The Manufacturing and Installation Phase is designed to reward production and installation of products meeting the L-Prize technical requirements. Up to four competitors earning the most points based on innovation, U.S. content, production, and installation will share an award of $10 million. Like the Prototype Phase, the Manufacturing and Installation Phase will feature two separate tracks: a luminaire track and a connected systems track. Under the rules, competitors could submit an entry for one track or separate entries for both tracks, and DOE will evaluate each track’s submissions independently.Original L-Prize Competition
60W Competition
The original L-Prize Competition, launched in 2008, sought LED replacements for the common 60-watt light bulb. In late 2009, the L-Prize competition received its first entry, from Philips Lighting North America. The 2,000 samples submitted by Philips went through a rigorous 18-month evaluation that included industry-standard photometric testing, stress testing under extreme conditions, and long-term lumen maintenance testing at elevated temperatures. In addition, field assessments were conducted by L-Prize partners to see how the product performed in real-world settings. The Philips entry met all requirements and, in August 2011, was declared the L-Prize winner in the 60W replacement category. The product became available in the retail market on April 22, 2012 (PAR38 and 21st Century Lamp Competitions
The L-Prize competition to develop LED replacements for PAR38 halogen lamps was launched but received no entries and was suspended in 2014. The 21st Century Lamp competition was never opened.References
