Due to a high volume of SSL and Hort applications, initial and comprehensive review timeframes are currently extended by 10 days each. Beginning April 11, review priority will be given to applications updating V5.0 products to V5.1, which may also impact review timeframes for all other SSL application types. Any other applications submitted between April 11 and May 1 will not begin the initial review process until the first week of May.

Whitepaper: 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. This whitepaper describes 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.

Key Takeaways
  • The lighting industry needs an integrated approach to solving the unintended negative consequences of light pollution on the natural environment.
  • Variation and lack of standardization in NWL lighting and LED chip terminology and metrics make inclusion of NWL in the LUNA Technical Requirements impossible at this time.
  • Recommendations for standardizing NWL metrics and terminology in the lighting industry.
