The Union City, Calif.-based Union Sanitary District approached LEDtronics to explore energy-saving lighting solutions throughout its 33-acre wastewater treatment facility. Following a site survey, LEDtronics recommended possibilities for a variety of energy-efficient LED lighting solutions to replace HID and fluorescent lamps around the plant, such as for post-top lamps, shoebox fixtures in parking lots and other traffic areas, wall-packs on several buildings and various types of indoor and outdoor lighting.
