High-Bay Lighting

High-bay lighting—defined as indoor lighting in spaces with ceilings higher than 25 feet—is used in a variety of applications, including big-box stores, school gymnasiums, sports venues, warehouses, and manufacturing facilities. High-intensity discharge (HID) and fluorescent lighting still dominate the high-bay market, but light-emitting diodes (LEDs) are making inroads. LEDs can be cost-effective because long operating hours lead to higher energy and maintenance savings, and high-bay environments often provide opportunities to control light levels based on occupancy and daylight harvesting—which LEDs can do very well. Although earlier LED products didn’t provide enough light for most high-bay applications, some of the latest products can replace up to 1,000-watt metal halide (MH) luminaires.
