Dark Sky International promotes five core principles for responsible outdoor lighting: (1) Light must have a useful purpose; (2) Light should be targeted specifically to its intended use to avoid spill light and sky glow; (3) Light should be kept at the lowest level necessary to achieve its purpose; (4) Light should be controlled by turning it on only when needed or dimming after hours; (5) Warm color temperatures should be used because blue light scatters more in the sky and causes greater sky glow. These principles form the foundation for Dark Sky International's programs, including the International Dark Sky Places certification program, which has certified 222 locations worldwide across 22 countries, and the Dark Sky Approved programs for sports lighting, luminaires, and lodging facilities.
