DarkSky Certification
At LSI, sustainability is built into every solution we design. As part of our mission to create environmentally responsible lighting, we proudly support and align with the principles of DarkSky International.
By engineering products that meet these high standards, we help reduce light pollution and protect the natural nighttime environment. We do so without sacrificing performance or safety. Our approach reflects a long-term commitment to sustainable lighting.
Compliancy Requirements
DarkSky compliance is all about responsible outdoor lighting through solutions that are useful, targeted, controlled, and warm-colored. DarkSky International’s specific compliance requirements are:
- No Uplight: Fixtures must emit no light above 90 degrees from the horizontal plane, preventing unnecessary skyglow.
- Directional Control: At least 85% of total lumens must be directed downward toward the intended target area.
- Glare Control: Glare levels must not exceed 1,000 candelas when measured from the designated glare evaluation offset distance for each targeted area.
- Uniformity: The average illuminance on the targeted area must not exceed 10% above the average target illuminance level.
- Spectrum Requirements: Fixtures must have a maximum correlated color temperature (CCT) of 5700K, minimizing blue light and reducing skyglow.
- Smart Controls: Lighting systems should include remote access control capabilities, such as those operable via smartphones or similar mobile devices.
LSI’s Solution
LSI works to support this initiative by designing lighting solutions that align with these guidelines, all while maintaining safety and visibility. Our commitment to DarkSky principles helps reduce light pollution, protect ecosystems, and improve human well-being, ensuring outdoor spaces support long-term environmental and community well-being. LSI does this by:
- Mitigate Uplight and Glare: Our fixtures feature specially engineered optics that significantly reduce uplight and glare, helping preserve night sky visibility while maintaining high-quality lighting.
- Targeted Light Distribution: LSI offers a range of shielding options that allow light to be focused exactly where it’s needed, avoiding light trespass and enhancing visual comfort.
- Compliant Color Temperatures: We provide a variety of CCT options, all below the 5700K maximum required for DarkSky certification and we offer true turtle amber solutions that limit blue light emissions and support ecological preservation.
