Sample Language for Light Pollution Mitigation Bylaws and Ordinances
Outdoor lighting ordinances, bylaws, and other community policies can help mitigate light pollution and negative impacts on wildlife, address light and energy equity issues, and provide guidance to help select products that meet the community’s needs. Written policies that specify what type of light is acceptable during nighttime hours clarifies expectations for product selection and verification. This resource was created by the DLC to provide sample language that can be used by communities as a starting point in creating their own light pollution bylaws or ordinances, and modified to meet the specific needs of the community or municipality.
In this Resource
- Provides generic language that can be included in written policies that specify what type of light is acceptable during nighttime hours clarifies expectations for product selection and verification.

Journal Article: Specifying non-white light sources in outdoor applications to reduce light pollution
This journal article, originally published in Leukos on January 5, 2023, proposes a specification structure for amber light sources to increase the precision of language used in the industry, and encourages lighting standards development organizations to consider standardizing such a system. It also demonstrates that non-white light sources with well-defined chromaticity ranges outside of the ANSI C78.377-2017 quadrangles may be useful for reducing wasted light that causes sky glow, a phenomenon that is associated with approximately $7 billion in wasted energy and nearly 66 million metric tons of CO2 emissions annually.
Key Takeaways
- A call for the lighting industry to consider developing industry consensus definitions and standards for “amber" light sources.
- Methodology for expanding ANSI standard CCT chromaticity bins to include three new bins: 1800K, 2000K, and PC Amber.
- Discussion of why CCT alone is not an adequate representation of the spectral composition of light, and the wide range of potential impacts to sky glow.

Outdoor Lighting Ordinances
The DLC conducted research to identify locations with published outdoor lighting ordinances to mitigate light pollution. Check the map to see if you have an outdoor lighting ordinance in your area.
Key Takeaways
- Learn more about what an outdoor lighting ordinance is
- Check the map to see if you have an outdoor lighting ordinance in your area
