Addressing Light Pollution Alongside Energy Savings

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 sets 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.
