Experts Warn Of Health Risks As Chicago Switches To LED Streetlights

Chicago officials say 270,000 old streetlights will be replaced with energy efficient LED lights over the next four years. But health and environmental advocates warn of problems if the wrong LEDs are chosen. Last month, the city rolled out seven pilot sites to demonstrate the proposed lights and gather public comments. But the comment period was set to end on Dec. 31, just two and a half weeks after it began. After complaints from residents, and questions from WBEZ, the city agreed to extend the comment period to Jan. 9.
