For years, the standard method of lighting gymnasiums has been the 400W Metal Halide High Bay. This has led to gyms with deteriorating light levels and poor playing conditions that are expensive to operate. New technologies have allowed lighting designers to specify T5 High Output (T5HO) Fluorescent High Bay Fixtures in place of the more inefficient metal halide fixtures. This shift has reduced the power consumption of gymnasium lighting systems, provided better quality light for all sports acti …
