Media Center: About the DLC
The DLC is a non-profit organization improving energy efficiency, lighting quality, and the human experience in the built environment. We collaborate with utilities, energy efficiency programs, manufacturers, lighting designers, building owners, and government entities to create rigorous criteria for lighting performance that keeps up with the pace of technology. Together, we’re creating solutions for a better future with better lighting.
Our mission is to achieve energy optimization by enabling controllability with a focus on quality, people, and the environment. The DLC’s many initiatives include three Qualified Products Lists for energy efficient lighting technology: Solid-State Lighting, Networked Lighting Controls (NLC), and Horticultural Lighting. We also offer an extensive library of resources, research, and tools that help accelerate the adoption of energy efficient, quality lighting solutions.
This FAQ document answers questions such as: what are the benefits of non-white light, why are non-white light sources not currently included in the LUNA Technical Requirements, and what are the necessary steps for the DLC to consider including these sources?
This executive summary pulls out the most important takeaways from the DLC's whitepaper, "Non-white Light Sources for Nighttime Environments." This summary is designed for those who do not want to dig deep into the science, and 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.
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.

Logo Usage & Guidelines
The DLC Program Logo is intended for use by:
- DLC Members
To indicate membership in the DLC Program on DLC Member webpages.
- Lighting Testing Laboratories
To indicate available product testing services necessary for manufacturers to submit an application to the DLC QPL. Laboratories must meet the DLC accreditation requirement to display the logo. The DLC Logos and Trademarks may not be displayed in test reports or be used in a manner that implies the DLC endorsement of a laboratory or its services.
Addition use of the DLC Program Logo will be assessed on a case-by-case basis. Please contact firstname.lastname@example.org.
