Whitepaper: Non-White Light Sources for Nighttime Environments

LDS DLC Logo

May 19, 2022

The lighting industry needs an integrated approach to solving the unintended negative consequences of light pollution on the natural environment. In response to this need, the DLC has published a whitepaper that seeks to describe the landscape for a small but promising part of the solution: non-white light (NWL) LED light sources.

This whitepaper provides an overview of the state of the science and current recommendations for NWL light sources in outdoor lighting applications, as well as why the DLC is not addressing NWL LED luminaires in LUNA at this time. The paper suggests next steps to address gaps in existing research, standards, and guidelines that would make qualification feasible in the future.

Full Technical Whitepaper

The full whitepaper is recommended for individuals who are familiar with technical lighting science and terminology, and who want to understand the full scope of the non-white light research performed by the DLC. The whitepaper explains the methodology used to for the NWL market review and outlines the additional technical research needed in order to consider qualifying NWL sources under LUNA.
