The International Dark-Sky Association (IDA) was founded in 1988 with a mission to preserve and protect the nighttime environment and our heritage of dark skies through environmentally responsible outdoor lighting.

IDA’s Fixture Seal of Approval program certifies outdoor lighting fixtures as being Dark Sky Approved, ensuring they minimise glare while reducing light trespass and skyglow. All products approved in the program are required to be fully shielded and to minimise the amount of blue light in the nighttime environment.

The current criteria for the program has been in operation since 2016 and of all the participating companies worldwide to date, LIGMAN has larger number of IDA certified products! Look out for the Dark Sky Approved Seal

Please Note: For IDA project compliance, in order to meet the terms of the fixture FSA and thus meet Dark Sky Approved criteria, fixtures must be specified with 3000K CCT or Warmer (plus Amber, or warm filtered) LED sources, fixed luminaire mounts must be ordered and the fixtures must be site orientated so that no light is directly emitted above the horizontal plane.

To check the full compliance requirements of the luminaires and their use, please find the full IDA FSA criteria here:

If required, LIGMAN’s in-house design team can offer assistance in product selection and lighting calculations to aid project compliance to IDA criteria.

Certified LIGMAN products all display the IDA’s Fixture Seal of Approval (FSA) denoting the current standard’s date and Dark Sky Approved
