New DarkSky regulations are being implemented in various communities, including Greenwich, Connecticut, where the new lighting guidelines took effect on March 27, 2024. These regulations are designed to reduce light pollution’s impact on nocturnal wildlife and human health by establishing strict standards for outdoor lighting fixtures, brightness levels, use of timers, and color temperature. Greenwich has become Connecticut’s first “Lights Out Community” under these new rules. The DarkSky initiative seeks to mitigate the disruption caused by artificial lighting, with added restrictions on landscape and building façade uplighting in residential projects. To ensure compliance, integrators must address specific questions regarding their lighting applications, focusing on functionality, targeted use, and warmth of color. Overall, these regulations are part of a broader effort to protect ecosystems and promote sustainable lighting practices, aligning with health-conscious strategies that enhance both human and wildlife circadian rhythms.
