"Our objective was to find an LED product that could replace our existing metal halide lamps while reducing energy consumption, increasing light levels, and improving light quality. So far, this pilot project has succeeded on all three fronts, and the findings are helping us to plan for expanded use of LED technology at this and other facilities."
