An Act To Promote Responsible Outdoor Lighting

LD 1934 requires public entities in Maine (like towns, schools, and state agencies) to install or replace outdoor lighting that meets specific standards starting October 1, 2026. It limits brightness to 125% of recommended levels, mandates fully shielded fixtures for bright lights, bans nonessential lighting (like decorative signs or holiday lights) after 10 PM, caps color temperature at 3,000 kelvins, and restricts light trespass near protected areas to 0.1 lux. The bill directly affects how public facilities illuminate streets, parks, and buildings, aiming to reduce light pollution and energy waste. Key provisions include requiring shielded fixtures for lights over 1,000 lumens and ensuring sports lighting confines most light to the field area.
