Xcel installing LED streetlights in Stillwater
brighter and cheaper streetlights. Xcel Energy crews on Monday were at the intersection of South Fourth and West Oak streets to begin the conversion of about 700 streetlights to more energy-efficient LEDs, or light-emitting diodes. The conversion is expected to take about a week, weather permitting. After Stillwater, lights in Lake Elmo and Oak Park Heights will be switched.
