Overview

Challenge Overview

The Lighting Prize (L-Prize) is designed to advance the U.S. clean energy economy for next-generation LED lighting, encouraging innovators and researchers to engage in advanced lighting system development that leads to transformative designs, products, and impact. The L-Prize will reward innovations that move rapidly to improve lighting performance, resulting in energy, carbon, and cost savings for American businesses and consumers.

The first Lighting Prize was awarded by the U.S. Department of Energy (DOE) in 2011, recognizing a high-efficiency LED replacement for the traditional 60-watt A19 incandescent bulb. Today, commercially available LED lights are competitive with all other lighting technologies, but the full technical and application potential of solid-state lighting (SSL) still far exceeds today’s products. Advanced interoperable lighting systems have the potential to better manage lighting energy use, integrate with other building systems, streamline maintenance and operations, and even respond to electric grid signals, increasing the value and resiliency of buildings. The L-Prize, a successor to the first Lighting Prize, seeks to unlock the additional potential to combine high-luminaire efficacy with exceptional lighting quality, data-driven control and functionality, innovative design, construction, and grid flexibility for the future of illumination in commercial and institutional buildings. In addition to these technical innovations, the L-Prize also invites innovation for diversity, equity, and inclusion in how systems are designed, produced, deployed, or installed.

The L-Prize targets commercial sector lighting, which accounts for 37% of national lighting energy use, and encourages lighting innovators to design lighting systems with breakthrough energy efficiency, quality, functionality, and sustainability. A full realization of SSL technology potential envisions LED lighting products manufactured with significant domestic materials, while demonstrating exceptional energy efficiency, data connectivity, seamless lighting control, excellent visual quality, and design for recycling and remanufacturing.

DOE’s Building Technologies Office invites lighting innovators to participate in this new competition to bring tomorrow’s lighting into today.

Winning systems must innovate and demonstrate exceptional achievement across all areas.

 

 

Prize Structure

The L-Prize consists of three distinct phases that will award a total of up to $12.2 million. Participation in initial phases is not required to be eligible for subsequent phases.

  1. The Concept Phase invites innovative concept proposals from potential competitors.
  2. The Prototype Phase seeks prototype products, emphasizing technological innovation and presenting the opportunity and the challenge to think outside standard forms, materials, and price points of commercially available luminaires.
  3. The Manufacturing and Installation Phase will reward production and installation of real products meeting the L-Prize technical requirements.

Participation in initial phases is not required to be eligible for subsequent phases. In addition, teaming opportunities will connect researchers and innovators with manufacturing partners, contractors, utilities, energy service companies, and others interested in production and installation of lighting systems meeting the L-Prize requirements.

L-PRIZE UPDATES: CONCEPT PHASE WINNERS, PROTOTYPE PHASE COMING SOON

Feb. 11, 2022, 1:52 p.m. PST by NREL Challenge

Congratulations to the L-Prize Concept Phase winners, announced on February 3 by U.S. Secretary of Energy Jennifer Granholm at the DOE Solid-State Lighting Workshop. 

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.

 

Coming Next: Prototype Phase

Looking ahead, the subsequent phases of the L-Prize will present fresh opportunities for awards and recognition. All eligible entrants are welcome to participate in any of the L-Prize phases and participation in one phase is not required to be eligible for another. 

Phase 2, the Prototype Phase, opens in June 2022 and calls for prototype lighting systems allowing hands-on evaluation for technical performance and innovation. We are currently preparing for the next phase launch, incorporating feedback and experience from the first phase. Stay tuned for more details!


L-Prize Concept Phase Winners Announced!

Feb. 3, 2022, 8:44 a.m. PST by NREL Challenge

We’re excited that four teams have been selected and announced as L-Prize Concept Phase winners by the U.S. Department of Energy. These teams were each awarded a $20k cash prize for meeting technical requirements across multiple categories, including feasibility, technical performance, and innovation. 

In the Concept Phase, lighting innovators were invited to create next-generation LED lighting concepts designed to advance the U.S. clean energy economy and leading to transformative designs, products, and impact. The next phase of the contest, the Prototype Phase, calls for prototype lighting systems allowing hands-on evaluation for technical performance and innovation. The Prototype phase is open to all interested competitors.
