NUVO Lighting 65-797R2 240W UFO LED High Bay, 4000K, 33360 Lumens, 120-277V, White Finish

One model covers both. The 65-797R2 has a universal 120V-277V driver, so the same fixture wires into 120, 208, 240, or 277 volt single-phase service without ordering a voltage-specific version. That is what makes it practical to standardize across a warehouse where the shop side is 277 and the office side is 120.

It ships ready to pendant hang or surface mount, and NUVO includes a locking hanging hook plus a 6 foot power whip in the box, so you are not sourcing a cord set separately. The whip measures 72 inches. At 6.42 lbs the fixture is light enough for a single installer on a lift, and a standard threaded rod, chain, or aircraft cable drop off a J-box handles the support.

It carries a wet location rating and is cULus safety listed, so damp and wet indoor environments are within its rating. NUVO still classifies it as an indoor fixture, so use it under roof in places like wash bays, loading docks, and cold storage rather than fully exposed outdoors.

Dimming is supported, so it can go on a 0-10V control or an occupancy sensor scheme for a lighting control retrofit. Color temperature is fixed, though: this is a 4000K fixture and it is not CCT selectable, so if you need 5000K for a shop floor you have to order a different model rather than flipping a switch on the housing.

Work from the output: each 65-797R2 delivers 33,360 lumens at 240 watts, which is about 139 lumens per watt. For a general warehouse target of roughly 30 footcandles, that is a lot of light per fixture, so spacing is usually driven by mounting height and rack layout rather than raw count. The 4000K neutral white color and 80 CRI are the typical choice for storage, manufacturing, and shop bays.

No. The LED is integrated into the fixture, with no socket or replaceable lamp, so at end of life you swap the whole unit. Rated life is 50,000 hours, which on a two-shift operation running roughly 4,000 hours a year is about a dozen years before you are planning a replacement.

The housing is 13.39 inches in diameter and 8.11 inches tall, so plan your drop length from the ceiling deck accordingly and keep it clear of sprinkler heads and rack tops. The body is die-cast aluminum, which is the heat sink for the LED, so leave air around the top fins rather than tucking it tight against a deck or insulation.

Yes. Lead is listed as a California Proposition 65 chemical for this fixture, which matters if you are procuring for a California facility and have to carry the disclosure through on submittals. The fixture is also RoHS compliant.

It comes in white only, with a utility-style round housing measuring 13.39 inches across. If your existing bays are 4000K, this one drops in visually with them; if they are 5000K you will see the difference side by side, since this fixture is fixed at 4000K and cannot be switched.
