Built for industrial ceilingsThe round UFO format exists for one reason: it concentrates a lot of light into a wide, uniform pool on the floor below, with a low-profile body that clears ductwork, sprinkler lines and crane rails. This fixture measures 15.4” in diameter and 7.28” in height, so it stays discreet even when mounted in rows down a warehouse aisle. The housing carries a white finish that reflects heat and blends into pale industrial ceilings, and a 3M cable comes supplied so the fixture arrives ready to connect. A sensor socket is supplied and capable, which means an occupancy or daylight-harvesting sensor can be added when your energy code or your client asks for one.
Light quality and beam controlUnder the PC lens, a 90° beam spread pushes light down and outward instead of letting it scatter at the ceiling, giving you consistent footcandles across racking, assembly tables and traffic lanes. CRI≥80 keeps colours honest, so inventory labels, colour-coded cable, safety markings and paint finishes are easy to read during a long shift. Field-selectable CCT gives you two selectable colour temperatures — 4000K for a neutral, comfortable white in shops and showrooms, 5000K for a crisp, alert white in warehouses, cold storage and sports spaces. Because the selection happens at install, one box on the shelf covers both looks.

Electrical and installationThe 120-347V auto-sensing driver is the detail electricians appreciate most: the same fixture wires into the service you find on site, which simplifies orders on multi-building projects and keeps spares universal. Selectable wattage does the same job on the photometric side — set 240W where the ceiling is lower or the rows are tight, step up to 300W over tall storage or an equipment bay. Always cut power at the panel before wiring, confirm the ceiling anchor or structural member can carry the fixture, space units according to mounting height (the higher the mount, the wider the spacing), and have a licensed electrician complete permanent connections. The IP65, wet location rating means dust, washdown mist and unheated spaces are not a problem.
Applications, family and documentationThink distribution warehouses and pick modules, machine and welding shops, agricultural buildings, arenas and gyms, car dealership service bays, recycling centres and food processing plants where the NSF rating matters. For a building with mixed ceiling heights, pair this unit over the tall bays with the
180W-200W-240W LED highbay in black, the
180W-200W-240W LED highbay in white or the
90W-120W-150W LED highbay over offices, mezzanines and lower service areas — same round UFO look throughout.
