DOE Announces Phase 1 Winners of L-Prize Lighting Competition

U.S. Secretary of Energy Jennifer M. Granholm announced the four winners in Phase 1 of the U.S. Department of Energy’s (DOE) Lighting Prize (L-Prize®) at the Building Technologies Office’s annual Solid-State Lighting Workshop. The L-Prize® is a $12.2 million prize lighting competition launched by DOE in May 2021. The L-Prize® is designed to spur groundbreaking innovation, domestic manufacturing, and the benefits of an inclusive, clean-energy economy for next-generation lighting solutions in commercial buildings.

The L-Prize Concept Phase winners are:

  • 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.
