Addressing Light Pollution

The DLC’s LUNA requirements establish criteria for using the highest quality outdoor lighting at night – lighting that minimizes light pollution, provides appropriate visibility for people, and limits negative impacts to the environment. In addition to the benefits that appropriate lighting can provide to our outdoor environment, there are also energy savings to be captured by only using the right type of light, and only where it is needed.

 

LUNA establishes performance requirements for specific categories of outdoor solid-state lighting so that energy efficiency programs, cities and municipalities, and all outdoor lighting decision makers can be confident that their selections save energy AND follow best environmental practices for nighttime lighting.

Why focus on light at night?

Light pollution unnecessarily contributes to climate change.

LUNA Policy Development

The DLC carefully evaluates every initiative for its impact on industry, environment, and end-users. We tap market experts, manufacturers, and other industry stakeholders to help establish verified, trustworthy requirements to keep the lighting industry at the forefront of carbon reduction efforts. The LUNA program will follow the DLC’s 6-step process to craft comprehensive criteria that address the needs of our energy efficiency program members and industry partners alike.
