Competition organizers recognized three luminaire prototypes and three connected systems prototypes.

The U.S. Department of Energy announced the winners of the L-Prize prototype phase on Oct. 25. The prototype phase is the second stage of the three-stage DOE competition, following the concept stage and preceding the manufacturing and installation phase.

The competition, which accepted entries from June 2022 to June 2023, is led by the DOE’s Building Technologies Office and administered by the National Renewable Energy Laboratory (NREL) with technical support provided by the Pacific Northwest National Laboratory. Points were awarded to entrants based on logistic, performance, and accessibility criteria, and awards were given in two categories: Luminaires and Connected Systems. The six winners shared a prize pool of $2 million, with the amount each was awarded listed with the winning entrants below.

Luminaire winners

Generation Flex: Light Without Compromise, Signify Innovation, Bridgewater, New Jersey

Award: $375,000

A modular, 3D-printed luminaire that achieves bidirectional connectivity and data communications through DALI D4i integration.

Low-Carbon Biodegradable Luminaire, Lightly, Boothwyn, Pa.

Award: $375,000

A linear luminaire that relies upon U.S.-sourced biodegradable alternatives to plastic and metal. Ben Rapkin, director of growth at Lightly, tells Architectural SSL of his company's win, “We are honored to be recognized for Lightly’s sustainable product designs, but there is a long way to go before we achieve our mission. Material sustainability is still an afterthought for many in the lighting community, and we will use these winnings to change the status quo.” (Read more about Lightly's innovative product line.)
