The American Medical Association (AMA) encourages communities to minimize and control blue-rich environmental lighting by using the lowest emission of blue light possible to reduce glare. The AMA recommends an intensity threshold for optimal LED lighting that minimizes blue-rich light. The AMA also recommends all LED lighting should be properly shielded to minimize glare and detrimental human health and environmental effects, and consideration should be given to utilize the ability of LED lighting to be dimmed for off-peak time periods.
The AMA report, titled “Human and Environmental Effects of Light Emitting Diode Community Lighting,” presents significant implications for the ongoing, worldwide transition to LEDs as the outdoor lighting technology of choice.
