What’s the difference between UFO (round) high bays and linear high bays for warehouse lighting?
Quick Answer
UFO high-bay fixtures are compact, round LEDs that pour a tight beam straight down from very high ceilings. Linear high bays are long, strip-style luminaires that throw a wider, rectangular pattern along aisles and shelving. Pick UFOs for open floors; choose linears for even coverage between racks.
Detailed Answer
UFO high bays are small, circular discs that hang from a single hook. Their lens produces a tight, symmetrical pattern (about 60-120°) that pushes light straight down from ceilings 20-60 feet high. They are perfect for open floor space, bulk storage, or any zone where you want the fewest fixtures, and their sealed housing resists dust and moisture.
Linear high bays look like the fluorescent strips they replace. Long 2- to 8-foot bodies hold rows of LEDs that spread light both downward and along the aisle. That rectangular beam fills the faces of racking, reduces shadows, and cuts glare for forklift drivers. Mounting heights of 15-40 feet and sensor-ready channels make them a favorite above pick lines and workstations.
Choosing the right style depends on ceiling height, aisle direction, and foot-candle targets. UFO units cost less per fixture and need fewer mounting points, while linears offer better uniformity and vertical illumination. Both LED options slash energy use up to 70% compared with metal-halide and qualify for common rebate programs.
