Cities respond to AMA warning on LED lighting

Some cities are looking closer at LED lighting after a warning from the American Medical Association, reports The Washington Post. The AMA's warning, issued in June, cautioned that while there are energy efficiency benefits associated with LED lighting, some LED lights may be harmful when used as street lighting. The AMA said high-intensity LED streetlights — such as those in places like Seattle, Los Angeles, New York City and Houston — emit a large amount of blue light that appears white to the naked eye and create worse nighttime glare than conventional lighting. "Discomfort and disability from intense, blue-rich LED lighting can decrease visual acuity and safety, resulting in concerns and creating a road hazard," the group said.
