Power management company Eaton today announced that it has helped improve the lighting performance and energy efficiency in a campus recreation facility at the University of Illinois at Urbana-Champaign. By replacing almost 400 lighting fixtures in three gymnasiums at the Activities and Recreation Center with Metalux™ HBLED high-bay light-emitting diode (LED) luminaires, the university’s projected cost avoidance is estimated to be as high as $70,500 annually.
