Formed in 1988, the International Dark-Sky Association is the authoritative voice on light pollution. IDA educates lighting designers, manufacturers, technical committees, and the public about light pollution abatement. The IDA recognizes that the best way to accomplish the goal of protecting and restoring our natural night environment and our heritage of dark skies is through promotion of quality outdoor lighting. It is in this spirit that they have developed the Fixture Seal of Approval (FSA) program for dark-sky friendly fixtures.

The Fixture Seal of Approval provides objective, third-party certification for luminaires that minimize glare, reduce light trespass, and don’t pollute the night sky.
