Executive Summary: Non-white Light Sources for Nighttime Environments

The lighting industry needs an integrated approach to solving the unintended negative consequences of light pollution on the natural environment. The DLC recently published a whitepaper describing the landscape for part of that solution: non-white light LED sources. Existing lighting standards must be updated to include NWL sources in order for the DLC and other stakeholders to evaluate these products using a consistent framework. The whitepaper outlines the necessary developments required for the DLC to address these types of products in the future. The executive summary is provided here to pull out the most important takeaways from the whitepaper for those who do not want to dig deep into the science. The executive summary includes an overview of current recommendations for NWL sources in outdoor lighting applications and what you need to know about the state of NWL research.
