You run an ice rink, a stadium, or some other kind of sports arena, and you’re still using metal halide light fixtures? You have no idea what you have been missing. But get ready for the best part: The lights save a ton of energy and money. The old metal halide fixtures consumed 263,000 kilowatts of power annually. The new LED ones? During the 2012-2013 season, the power draw was reduced by 87 percent to 32,000 kilowatts. The savings is huge.
