NUVO Lighting 65-783R1 150W UFO LED High Bay, 20850 Lumens, 4000K, 120-277V, 0-10V Dimmable, Black Finish

The 65-783R1 is a universal-voltage driver rated 120V to 277V, so it runs on 120, 208, 240 or 277 volt circuits without changing the fixture. That covers most commercial and industrial panels. For 347V or 480V service you need a different fixture.

This NUVO UFO puts out 20,850 lumens at 150 watts, which is typically a one-for-one swap for a 400W metal halide fixture whose output has dropped with age. Color is 4000K neutral white with 80 CRI, so it reads cooler and cleaner than aging MH. Rated life is 50,000 hours.

It carries a wet location rating and is cULus safety listed, so moisture exposure is acceptable. NUVO still classifies it as an indoor fixture, so use it under cover (warehouse, wash bay, covered dock) rather than fully exposed outdoors.

The driver is 0-10V dimmable, so it pairs with a 0-10V low-voltage control: an occupancy or daylight sensor with a 0-10V output, or a 0-10V wall dimmer. It will not dim on a standard line-voltage phase-cut (TRIAC/ELV) dimmer. The 0-10V pair is a separate low-voltage run from the line conductors.

It is a ceiling-mount fixture and ships with 72 inches of supply wire, which gives you room to reach a junction box above the mounting point without splicing. The housing is die-cast aluminum and the fixture weighs 6.58 lbs, light enough for a single hook, chain, or threaded pendant drop. Confirm what mounting accessory your structure needs, as the hook or chain is the part most often ordered separately.

No. The 65-783R1 is fixed at 4000K with no CCT selector switch. If you need to match 5000K fixtures already in the building, or want field-adjustable color, you need a CCT-selectable model instead. For a mixed facility, standardize on one CCT before ordering the lot.

No, the LEDs are integrated into the fixture; there is no socket, lamp base, or replaceable module. At end of life the whole luminaire is replaced. Rated average life is 50,000 hours, so at 12 hours a day that is roughly 11 years of service.

The fixture body is 11.81 inches in diameter and 8.19 inches tall, so plan for roughly a foot of round footprint plus the drop hardware and the 72 inch supply whip. In low-clearance spaces the 8.19 inch height is what limits how tight you can mount it to the deck.

It is RoHS compliant. It also carries a California Proposition 65 warning for lead, which is standard on many metal-housing electrical fixtures and matters if you are submitting documentation for a California job.

Black only, on a die-cast aluminum housing. There is no white or bronze option for the 65-783R1, so if a ceiling needs to disappear visually the black body is what you get. The cast aluminum body also does the heat sinking for the LEDs.
