The DLC will be switching to a new application portal for SSL and Hort applications on January 31, 2022. Any SSL and Hort applications that have been created must be submitted by close of business on January 31 in order to complete their review through the old portal. Any applications that remain unsubmitted on February 1 must be recreated in the new portal. There will be no change for NLC applications at this time. Click for more details.

The DLC is pleased to release the final requirements document for LUNA Version 1. LUNA is a new set of requirements that establishes performance thresholds and reporting criteria for categories of outdoor lighting intended to not only reduce energy use, but also help minimize light pollution, provide appropriate visibility for people, and limit negative impacts to the environment. LUNA is a subset of SSL V5.1 qualified products. Learn more about LUNA.

The DLC’s LUNA requirements establish criteria for a classification of qualified outdoor lighting that not only meet the SSL V5.1 requirements for energy efficiency and lighting quality, but also have attributes that may help limit light pollution, sky glow and light trespass.

Three goals of LUNA:

  • Minimize lighting energy use. Baseline efficacy thresholds of SSL V5.1 and additional dimming and control requirements ensure efficient use of lighting energy, which will help efficiency programs meet savings goals and end users reduce operational costs.
  • Provide appropriate visibility for people. SSL V5.1 requirements for spectral quality, plus reporting of BUG rating, spectral power distribution, and intensity distribution, will allow specifiers to choose the right product for the application so that installations meet recommended practices and voluntary guidelines.
  • Minimize light pollution. Requirements for light distribution, spectral characteristics, and dimming control decrease the light scattered into the atmosphere, resulting in darker skies and more controlled illumination to support wildlife, stargazers, and astronomers.
