LED UFO high bays take their name from the circular, disc-shaped housing that distinguishes them from linear alternatives. The compact round design makes hook, chain, or conduit mounting fast and straightforward, and they work well in open-plan warehouses, manufacturing cells, gymnasiums, and storage facilities with ceiling heights above 15 feet.
The round symmetrical beam pattern distributes light evenly in all directions, which suits grid-based layouts where fixtures are spaced at regular intervals across a floor plan. Most UFO high bays are sold as complete self-contained units with an integrated LED driver, making them a direct one-for-one swap for existing round metal halide or HPS high bays. Wattages typically run from 100W to 240W, replacing 250W to 1000W HID sources at a fraction of the energy cost.
Look for fixtures with an adjustable mounting bracket if your ceiling structure requires angled mounting. Many commercial UFO high bays also include a 0-10V dimming wire and a built-in motion sensor hook-up for occupancy-based controls, which can push effective energy savings well above the already substantial source-efficiency gains.
