Fixture Seal of Approval Application

Fixture Seal of Approval Criteria as of May 17, 2021

To receive the FSA, all of the following criteria shall be met.


General:IDA's Fixture Seal of Appeal logo that says, "Dark Sky Approved."

To be listed, a fixture must be fully shielded and emit no light above the horizontal plane. There shall be no sag or drop lenses, side light panels, uplight panels, etc. Approved fixtures shall employ warm-toned (3000K and lower) white light sources or may employ amber light sources or filtered LED light sources. If other cct’s or mounting options are available for the luminaire, a notation needs to be made on the web page, spec sheets, and order forms that 3000k or warmer, and fixed mounts must be ordered for IDA certification compliance.

For Commercial Luminaires:

    • Photometric files are needed to validate performance characteristics.
    • There is an uplight allowance of 0.5% of total output or 50 lumens; whichever is lower, with no more than 10 lumens in 90-100 degree UL zone. Allowable uplight as a byproduct of the structure and not the source, i.e. the fixture is fully shielded.
    • Street and area lights must have a pre or post-installation shielding option.
    • Luminaires are required to have fixed mounts to ensure they are mounted as photometered. There can be up to + or- 10-degree adjustment for leveling if needed.
    • Luminaires must have dimming capability to 10% of full rating.
    • Light sources shall have a maximum correlated color temperature of 3000K.
    • Luminaires must have Safety Certification by an independent laboratory.

For Residential Luminaires:

    • Uplight allowance: Not to exceed 50 lumens from source reflection or support structures. Source is not visible from the horizontal plane, i.e. the fixture is fully shielded. 
    • Require fixed mounts to ensure luminaire is mounted as photometered.
    • Light sources shall have a maximum correlated color temperature of 3000K.
    • Safety Lab Certification

Innovation: This is to encourage a Best in Class lighting development that significantly reduces light pollution and nocturnal habitat disruption.

    • No Uplight allowance, BUG rating, U-0
    • Dimmable to 1% of full rating
    • Smart controls that meet program purposes
    • No more than 7% of visible emissions in 380-520nm

    Wildlife Tuned:

      • Presently to recognize need of Florida turtle lighting approval program
      • If research proceeds as expected and spectral sensitivities are known, this feature will be in place for future species-specific needs.
      • No uplight, BUG U-0
      • Sea turtle specific spectrum: 0% less than 565nm


    • Company Registration for FSA Certification (Fixture or Device) is $2,500.00.
      This one-time fee applies to fixture applications received on or after January 1, 2016, from
      companies that have never previously applied for a FSA certification.
    • FSA Certification is $250.00 per product family.


    • Photometric (.ies) files must be submitted for each fixture seeking certification. Only one fee is required per product family — that is, a group of fixtures having the same body but differing distributions and/or lumen outputs — not per individual SKU or specifier code.
    • Recertification is required when new photometric data are obtained owing to performance changes for candle power distribution that are greater than 10%.
    • Product identification or specifier code(s) must be provided for each listed fixture with a CCT of 3000K or less.
    • Recertification is required when new photometric data (intensity distributions) are obtained demonstrating a change of 10% or more candela at any measured angle.
