Bill 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. Provides that the act does not apply if it is necessary to use uplighting for statuary lighting and historical façade lighting. In cases where uplighting is the only viable solution for these items, the lighting should have a color corrected temperature of no more than 2,700 degrees Kelvin, must be minimized to no more than 25% above ANSI/IES standards, must exceed an illuminance of one lux as measured at ground level both horizontally and vertically at the property boundary, and must be extinguished every night no later than 12:00 a.m. Provides that, after January 1, 2027, any new placement or replacement of uplighting of State historic statuary and State historical façade lighting shall be approved by the State Historic Preservation Office. Makes other changes.

AI Summary

This bill amends the Responsible Outdoor Lighting Control Act to require that all new outdoor lights, or "luminaires," purchased or installed after June 30, 2032, must emit light with a color temperature of 2,700 Kelvin or less, which generally results in a warmer, less blue-toned light. The bill also creates exceptions for uplighting used on statuary and historical building facades, allowing it only when it's the only viable option, and stipulating that such lighting must also be 2,700 Kelvin or less, be minimized to no more than 25% above standard brightness levels, not exceed specific light trespass limits, and be turned off by midnight each night. Furthermore, after January 1, 2027, any new or replacement uplighting for state historic statuary and facades will require approval from the State Historic Preservation Office.
