Citing Health Concerns, Some Cities Consider Dimmer LED Streetlights

In the last several years, New York, Los Angeles, Houston, Seattle and other U.S. cities have installed high-intensity, white LED streetlights. In all, at least 13 percent of outdoor lighting is now LED, and many communities that haven’t yet made the switch are rushing to do so. But health concerns, heightened by a recent warning by the American Medical Association (AMA), are giving pause to some local officials, spurring them to consider less-intense LED alternatives. Honolulu, Phoenix and smaller cities in Arizona, California, Florida and Massachusetts are among those who are taking the health warnings seriously.
