Summary

Amends the Responsible Outdoor Lighting Control Act. Provides that all new luminaires purchased or installed after June 30, 2032, must have a correlated color temperature less than or equal to 2,700 Kelvin.

Bill Overview

Analyzed Economic Effects

8 provisions identified: 5 benefits, 1 costs, 2 mixed.

Protecting habitats from stray light

Starting January 1, 2025, no artificial light above 1 lux may trespass onto land or waterways labeled habitat, reserve, natural area, open space, or wilderness. This limit is checked at ground level both horizontally and vertically.

Safety and emergency lighting exceptions

Starting January 1, 2025, state agencies may allow lighting that does not meet the law when safety or security cannot be fixed another way. Correctional and hospital facilities may use necessary safety lighting that follows their standards. Fire, police, rescue, and repair crews may use temporary lighting for emergencies or road work. Airports and maritime operators may use lighting needed to meet FAA or nautical safety rules.

Stricter outdoor lighting on state property

Beginning January 1, 2025, state‑funded outdoor lights and lights on DNR land must meet strict rules. Fixtures must be fully shielded with an IES BUG rating, send less than 1% of light above 80 degrees, and none above 60 degrees. Light at the edge of the property must be 1 lux or less at ground level. New lights must be 2,700 K or cooler through June 30, 2032, and 2,200 K or cooler after that. Overall and façade lighting must be no more than 25% above ANSI/IES or USDOT guidance, and façade lighting must point downward.

Historic and statue lighting limits

Starting January 1, 2025, uplighting for statuary or historic façades is allowed only when it is the only viable option, uses 2,700 K or cooler lamps, stays within 25% of ANSI/IES levels, meets the 1‑lux trespass limit, and turns off by 12:00 a.m. New or replacement uplighting after January 1, 2027, must be approved by the State Historic Preservation Office. Existing decorative or ornamental historic lights may remain, but replacements must meet the law as much as possible while keeping the historic look.

Road projects favor reflective markings

Starting January 1, 2025, when planning new or replacement roadway lighting on state or DNR roads, authorities must check if reflective markings or signs can safely replace lights. They must use passive measures instead of lighting, except at intersections of two or more streets.

Short-term breaks for events and holidays

Starting January 1, 2025, active sports or show grounds may use lamps over 2,700 K during practices, matches, or events only. Lamps must be aimed or shielded to avoid glare and trespass and limit upward light. Temporary seasonal holiday lighting is allowed for up to 45 days around the holiday season.

New rules for flagpole lighting

Starting January 1, 2025, new flagpoles must use downward‑facing lamps at 2,700 K or cooler. Existing upward‑lit flagpoles may use lamps at 2,200 K or cooler to reduce glare and trespass. When you retrofit an existing flagpole, you must convert it to meet the law.

Stricter local or federal rules control

Starting January 1, 2025, if a county or city has outdoor‑lighting rules that are equal to or stricter than this law, those local rules apply there. Federal law also overrides this law where it preempts it, and any stricter federal, State, or local law controls.
