The Program

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. We recognize that the best way to accomplish our 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 we 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. For a modest fee, IDA will evaluate the photometric data of any luminaire submitted by its manufacturer. When the fixture is approved, the manufacturer receives a certificate and the Fixture Seal of Approval. Manufacturers may use the FSA seal to promote and advertise their IDA-Approved™ dark sky friendly products.

For more information on the FSA program, its scope, and its criteria, and for our answers to your frequently asked questions, please refer to our FSA program package (Portable Document Format). Or contact us online.


Submit your dark sky friendly product to IDA for evaluation and certification. Join the Fixture Seal of Approval program before your competitors do!

To apply for the Fixture Seal of Approval, simply fill out the online application form and hit submit. IDA will then contact you after evaluating the photometric data and will give you instruction on the final steps. If you would rather submit the application by hard copy, just hit the "view as PDF" button in the upper right hand corner of the online application page and email or fax in the application.
