We recently head a briefing from Citizens for Responsible Lighting, a grassroots organization lobbying for healthy LED light options for Norfolk. The City of Norfolk Government is upgrading its lighting system to energy efficient LED lights, but in the process installing much brighter, whiter (cooler) lights, which have been shown to be unhealthy at night for residents, local wildlife, and our night sky visibility. We support the effort to get Norfolk and all the region's cities to install warmer, lower intensity LED lights, especially in residential areas and areas near parks and natural areas.
Dark Sky International has an excellent primer on Responsible outdoor lighting discussing the issue and their Five Principles for better lighting.
