This information has been collected by the Illuminating Engineering Society of North America (IESNA) and summarized by the International Dark-Sky Association. Please note that these values are recommendations, not standards. Standards are set at the federal, state, county, or community level. The IESNA does not set standards, though IESNA recommendations are often used by those who set standards.
