L-Prize Prototype Phase

In this phase, competitors were invited to submit working prototype systems that emphasized technological innovation and challenged entrants to think outside the standard forms, materials, and price points of commercially available products. Competitors could submit products in the Luminaire Track, the Connected Systems Track, or both. Entries were scored across multiple categories, including energy efficiency, connectivity and control, visual quality, environmental sustainability, and attention to diversity, equity, and inclusion (DEI) in lighting design, manufacturing, and application.

Six winners were selected based on their groundbreaking innovations, sharing an award of $2 million.
