American Made Challenges: L-Prize with the Department of Energy

May 14, 2024

l-prize
The L-Prize seeks to unlock that additional potential 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 and institutional buildings.

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 seeks to unlock that additional potential 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 and institutional buildings. In addition, all of the technical areas in the L-Prize carry with them an overarching commitment to driving equity, accessibility, and resilience in the design and deployment of luminaires and connected systems.

The L-Prize targets commercial sector lighting, which accounts for about 56% of national lighting energy use and challenges lighting innovators to develop solid-state lighting (SSL) systems with breakthrough lighting energy efficiency, quality, functionality, and sustainability. SSL technology has the potential to bring widespread deployment of lighting products with exceptional energy efficiency, connectivity, control capabilities, and visual quality that are affordable and accessible to a wide range of businesses and consumers.

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

Winning systems must demonstrate exceptional achievement across six distinct categories. Through the challenging criteria within these categories, the competition can directly influence the equity, accessibility, and resilience benefits of advanced lighting systems.

Prize Structure

The L-Prize will award a total of $12.2 million in cash prizes across three distinct phases.
  1. The Concept Phase invited innovative concept proposals from potential competitors. This phase is completed.
  2. The Prototype Phase invited physical prototype systems that emphasized technological innovation and challenged entrants to think outside standard forms, materials, and price points of commercially available products. This phase is completed.
  3. The Manufacturing and Installation Phase will reward production and installation of real products meeting the L-Prize technical requirements.

For the final phase, Manufacturing and Installation, participation in the first two phases is not required to be eligible.
