UFO high bay lights are built for spaces with high ceilings — warehouses, workshops, gyms, manufacturing floors and distribution centres. Round, compact, and hung from a hook or chain, they deliver high output straight down onto the working floor.Available 100W to 240W. A 150W UFO replaces a 400W metal halide high bay; a 240W replaces 1000W. Standard units run 100–277V, and high-voltage versions cover 277–480V for industrial three-phase supply.Selectable-wattage models let one fixture cover several output levels, which is useful when you are specifying before the final lighting layout is fixed. Five-year warranty across the range.
