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 (QPLs) for energy efficient lighting technology: LED 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.

Executive Summary: Choosing Both Energy Efficiency and Light Pollution Mitigation for Commercial Outdoor Lighting
There is a perception that, in a commercial retrofit setting, light pollution mitigating LEDs are less efficient and more costly than energy efficient LEDs, but in some cases you can have the best of both worlds. The DLC commissioned a study to research the impacts of LED applications that are both energy efficient and minimize light pollution as compared with products focused solely on energy efficiency. This executive summary provides an overview of the results of the research.

Choosing Both Energy Efficiency and Light Pollution Mitigation for Commercial Outdoor Lighting
There is a perception that, in a commercial retrofit setting, light pollution mitigating LEDs are less efficient and more costly than energy efficient LEDs, but in some cases you can have the best of both worlds. The DLC commissioned a study to research the impacts of LED applications that are both energy efficient and minimize light pollution as compared with products focused solely on energy efficiency. The study includes analysis of the impact on ROI, annual energy use, and energy costs.

Lighting Controls Best Practices
This resource explains the following basic networked lighting control strategies: dimming, high end trim, occupancy/vacancy sensing, scheduling, and daylight harvesting, and gives an overview of how to implement them to maximize energy savings.

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. - Other
Addition use of the DLC Program Logo will be assessed on a case-by-case basis. Please contact info@designlights.org.
