NY S05275

State agencies cannot install or replace permanent outdoor lighting fixtures unless they meet specific shielding and luminance requirements designed to reduce glare, sky glow, and light trespass.

Roadway and parking-lot lighting must be fully shielded, while building-mounted fixtures over 3,000 lumens must be fully shielded, and facade lighting must be shielded to the greatest extent possible.

Ornamental roadway lighting fixtures are limited to 700 lumens above horizontal plane, and all new fixtures must use only illuminance levels necessary for their intended purpose.

Exemptions apply to federal law preemptions, emergency and repair personnel, aviation/nautical safety, athletic lighting, security needs, fixture replacements, tunnels, and fixtures where compliant alternatives cost more than 15 percent greater over the system's lifetime.

The Office of General Services must submit a compliance report to the governor and legislature by June 1, 2017, and the law takes effect one year after enactment, excluding projects with prior final design approval.
