L-Prize awards points for use of D4i and Zhaga Book 20

The L-Prize, announced by the US Department of Energy (DOE), rewards data-rich, upgradeable luminaires based on Zhaga Book 20 and D4i. Zhaga and the DALI Alliance will explain details in a joint webinar on August 19.

Luminaires designed in compliance with D4i or Zhaga Book 20 will be rewarded with extra points during evaluation for the L-Prize, a lighting competition announced by the US Department of Energy (DOE) which has a prize fund of up to $12.2 million.

Luminaires submitted for the Concept Phase, which has a submission date of November 19, 2021, will be evaluated according to a number of topics including quality of light, connectivity, product life cycle and more.

One topic is standardized power and data connections, enabling sensors and other devices to be added to the luminaire. 

One point will be awarded for luminaires/systems that include standardized power, data, and sensor capabilities in compliance with D4i or ANSI C137.4.

A further point will be awarded for luminaires that incorporate a standardized sensor port and power/data connections in compliance with Zhaga Book 20 (which is based on D4i).

“DALI-based luminaires align very well with the L-Prize requirements,” said Paul Drosihn, DALI Alliance General Manager. “In addition to D4i, DALI enables white-tunable capability, standardized dimming, energy reporting, occupancy sensing and many other features specifically referenced in the L-Prize rules.”

Details of how D4i and Zhaga Book 20 can contribute to a successful L-Prize submission will be explained in a webinar presented by the Zhaga Consortium and the DALI Alliance on August 19, 2021.
