This bill mandates that outdoor lighting fixtures installed or replaced by State agencies, or at projects receiving State funds, must adhere to specific criteria aimed at reducing light pollution. The requirements include the use of fully shielded luminaires, limiting light emissions 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 by emergency personnel, nighttime work, or when a compelling safety interest cannot be addressed by other means.

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 road markers or informational signs, rather than installing new lighting fixtures. The provisions of this bill are set to take effect on the first day of the third month following its enactment, aligning with similar initiatives in at least 18 other states aimed at promoting energy conservation and protecting the natural nighttime environment.
