Seven Strategies to Minimize Negative Impacts of Outdoor Light at Night

The DLC’s LUNA requirements establish additional performance criteria for outdoor LED lighting that minimizes light pollution so that decision makers can be confident that their selections save energy, improve nighttime visibility, and protect the night. 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.
