Seven Strategies to Minimize Negative Impacts of Outdoor Light at Night

The DLC’s LUNA V1.0 Technical Requirements for outdoor solid-state lighting products establish criteria to enable the use of high-quality outdoor lighting at night to minimize light pollution, provide appropriate visibility for people, and limit negative impacts to the environment. In addition to these benefits, LUNA products can help capture energy savings by using the right type and amount of light, and only where and when it is needed. But even the best outdoor lighting product can fail to meet these objectives if not applied correctly. This resource provides high-level application strategies that go beyond the LUNA product requirements for energy efficiency program staff, contractors, distributors, and lighting practitioners who are interested in using outdoor lighting that is both energy efficient and reduces light pollution.
