Product Description

Who This Fixture Is For
This 240W Aries UFO LED high bay replaces 750W to 1000W HID fixtures in industrial spaces with 20-foot ceilings or higher. The round UFO shape distributes light evenly in a downward circle, which makes it well suited for large open floors and high ceiling environments where rectangular linear fixtures would create uneven coverage. With selectable wattage and three beam angle options through the optical system, a single fixture adapts to a wide range of mounting heights and applications. It's particularly suited for:
- Warehouses and distribution centers, where consistent floor illumination across wide aisles supports forklift operation and inventory work
- Manufacturing floors and factories, where shift work and machinery uptime demand reliable, code-compliant illumination
- Gymnasiums, sports facilities, and arenas, where high mounting and even floor coverage matter more than directional throw
- Big box retail, home improvement stores, and wholesale clubs converting from metal halide
- Aviation hangars, indoor riding arenas, and other tall-ceiling spaces where the IP65 rating handles dust and washdown environments
- HID retrofit projects where the goal is to match or exceed existing light levels at a fraction of the energy draw
The 120-277V input supports industrial circuits and includes a 6-foot cord with a 120V straight-blade plug. An optional 277V twist-lock plug is available at checkout for facilities standardized on 277V.

Major Benefits of the Aries UFO LED High Bay
Direct HID Replacement With Major Energy Savings
This fixture is engineered as a direct replacement for 750W to 1000W metal halide and HID fixtures, delivering up to 38,400 lumens at 240W. That's roughly a 70% to 75% reduction in energy use for equivalent or better light output, with no warm-up time, no lumen depreciation curve to plan around, and no ballast to fail. For facilities running fixtures 12 to 24 hours a day, the payback math is significant.
3-in-1 Optic With Selectable Beam Angle
The optical system supports three beam angles (60°, 80°, and 100°) selectable on the fixture itself. Narrower beams concentrate light for taller ceilings or aisle-focused applications. Wider beams spread light evenly for lower mounting heights or open floor plans. That flexibility means one SKU works in multiple project conditions without re-spec'ing fixtures.
160 Lumens Per Watt With DLC Premium
At 160 LM/W efficacy and DLC Premium listing, this is among the most efficient high bays in its class. DLC Premium qualifies the fixture for the highest tier of utility rebate programs, which, on a multi-fixture warehouse retrofit, can translate to meaningful incentive payments. Combined with the energy savings over HID, the rebate stack accelerates payback considerably.
IP65 Rated for Tough Environments
The IP65 rating means the fixture is dust-tight and protected against water jets from any direction, making it suitable for unconditioned warehouses, food processing facilities with washdown protocols, dusty manufacturing environments, and outdoor covered applications such as loading docks.
Multiple Reflector and Sensor Options
Beyond the no-reflector configuration, the fixture supports four reflector types (prismatic, aluminum, black aluminum, white aluminum) with or without a conical bottom lens, allowing designers to tune the light output for glare control or aesthetic match. Sensor options include PIR, microwave, and WareSense Blue Bluetooth, which is Warehouse Lighting's gateway-free Bluetooth mesh control system for zoned scheduling and group control across multiple fixtures.
FAQs: Aries LED UFO High Bay
How do I figure out how many of these I need and what spacing to use?
A common starting rule is to space fixtures roughly equal to the mounting height for uniform coverage. At a 25-foot ceiling, that means fixtures around 25 feet apart in both directions, dropping to closer spacing if you need higher footcandle targets like manufacturing or inspection work. Total fixture count depends on square footage, target footcandles, ceiling reflectance, and racking layout, which is why rough calculations only get you partway. Warehouse Lighting provides free photometric layouts using the actual IES file for this fixture. For large projects, it's recommended that you request a layout before placing an order, as LED retrofits often require fewer fixtures than older HID systems.
What's involved in claiming the utility rebate this fixture qualifies for?
Most utility rebate programs require pre-approval before the fixtures are purchased or installed, so the order of operations matters. Contact your utility's commercial lighting program, submit baseline information about the fixtures being replaced, get pre-approval, install the new DLC Premium fixtures (this one qualifies), then submit final paperwork including the spec sheet, DLC listing verification, and installation invoice. Programs typically pay $50 to $300 per high bay fixture, depending on utility and wattage reduction, with checks issued 4 to 16 weeks after final submission. Warehouse Lighting offers Energy Rebate Assistance and can help with the documentation side of larger projects.
Should I order the 120V straight blade plug or the 277V twist lock plug?
The 120V straight blade plug is included as the default and works on standard commercial 120V receptacles, common in smaller industrial buildings, retail back-of-house, and shops. The 277V twist lock plug is a $12 upgrade and is what most large warehouses and industrial facilities are wired for, since 277V is more efficient over long runs and reduces conductor sizing. If you're not sure what voltage your facility uses, check the breaker panel or ask the building electrician before ordering, since installing a 120V plug on a 277V circuit (or vice versa) will damage the fixture.
Does this fixture work with an emergency battery backup for code-required egress?
Yes, a separate EM Remote Conduit Box accessory (WL-LECV-UFO-40D-R-G3) is available for applications where the high bay is part of an emergency egress lighting plan, providing illumination during a power outage. This is usually required in manufacturing and warehouse spaces to ensure employees can safely exit during a power outage. The remote conduit box is sold as an accessory rather than a built-in option, so plan the installation with your electrician to confirm placement and wiring before ordering. Local code requirements vary, so checking with your AHJ on duration and coverage is worth doing before specifying quantities.
