L-Prize Prototype Phase

In this phase, competitors are now invited to submit physical prototype systems, emphasizing technological innovation and challenging entrants to think outside the standard forms, materials, and price points of commercially available products. Up to six competitors earning the most points for innovation exceeding minimum performance requirements will share an award of $2 million.

The Prototype Phase has two separate tracks: a luminaire track and a connected systems track. Competitors may submit an entry for either track or separate entries for both tracks. DOE will evaluate each track’s submissions independently. Participation in the prior Concept Phase is not required to be eligible for subsequent phases of the L-Prize.

Prototype submissions will be evaluated in person by the Expert Reviewer Panel for energy efficiency, lighting performance, functionality, and sustainability features. Competitors can earn points for exceeding the minimum technical requirements and for additional technical innovations and approaches to support diversity, equity, and inclusion.

The Prototype Phase Intent to Submit deadline is January 13, 2023, with Submissions due June 1, 2023.

Teaming Opportunities

The Prototype Phase also initiates a teaming opportunity for participants. A Teaming Request for Information (RFI) seeks parties interested in participating with or supporting L-Prize teams in the Manufacturing and Installation Phase. Manufacturing partners, materials or component suppliers, end-user installation host sites, utilities, energy service companies (ESCOs), installation contractors, and other interested parties are welcome. The teaming RFI will be open for the duration of the L-Prize competition, and a teaming partner list for competitors will be posted publicly under the L-Prize Resources and updated regularly.

Public Comment Period

DOE invites comments on the draft proposed requirements and timelines for the forthcoming Manufacturing and Installation Phase. A comment period will open at the beginning of the Prototype Phase and remain open until January 13, 2023.
