The debate on the benefits of LEDs intensifies

The American Medical Association Council on Science and Public Health recently released a report detailing the health impacts of light emitting diodes (LEDs) that emit excessive amounts of blue light. The Council reviewed the hazards of LEDs that emit heavy amounts of blue light; exposure to “blue-rich white light” can lead to increased risks for cancer, diabetes, and cardiovascular disease. The report, titled Human and Environmental Effects of Light Emitting Diode Community Lighting, presents new information about the risks of exposure to LEDs, and also provides insight on the environmental downsides of LEDs — somewhat ironic findings given that LEDs have been championed as more environmentally sustainable lighting than traditional bulbs.
