AI Summary

This bill, titled the "Dark Sky Act," amends existing law to establish new regulations for outdoor lighting purchased or installed with state funds, aiming to reduce light pollution. Beginning December 1, 2026, all new or renovated outdoor lighting fixtures purchased or rented with state funds, and any lighting installed on state-owned or managed land, must comply with specific "responsible outdoor lighting requirements." These requirements include minimizing light output, preventing light trespass onto sensitive areas, limiting the color temperature of light sources, and ensuring sports lighting confines light to the playing area. The bill also introduces exceptions to these rules for situations involving federal law, safety and security needs, temporary emergencies, historical lighting, and special events, with a process for state agencies to request exemptions from the Department of Central Management Services. The Act also updates definitions related to lighting standards, such as "ANSI/IES standards" (guidelines from the American National Standards Institute and Illuminating Engineering Society) and "IES BUG rating" (a system to classify how much light a fixture emits in different directions).
