This bill mandates that outdoor lighting fixtures installed or replaced by State agencies, or at projects funded by State resources, must adhere to specific criteria aimed at reducing light pollution. The requirements include the use of fully shielded luminaires, limiting light output to necessary levels as recommended by relevant authorities, employing full cutoff fixtures for lights exceeding 1,800 lumens, and considering energy conservation while minimizing glare and light trespass. Exceptions to these requirements are provided for temporary lighting used in emergencies, nighttime work, or when a compelling safety interest exists that cannot be addressed otherwise.

Additionally, the bill directs the Department of Transportation to evaluate whether the intended purpose of outdoor lighting along roadways can be achieved through alternative methods, such as reflective markers or signs, rather than installing new lighting fixtures. The provisions of this act are set to take effect on the first day of the third month following its enactment. This legislation aligns with efforts in at least 18 other states to mitigate light pollution, promote energy efficiency, and protect the natural nighttime environment.
