NUVO Lighting 65-783R2 150W UFO LED High Bay, 4000K, 20850 Lumens, 120-277V, Black Finish

The 65-783R2 is a 120-277V fixture, so it will run on 120, 208, 240 or 277 volt single-phase service without changing anything. It will not accept 347V or 480V. For a 480V building feed you need a step-down transformer or a 480V-rated high bay instead.

It ships with a locking hanging hook and a 6 foot whip (72 inch wire lead), so you can hang it from a J-box or threaded rod and make up the connection without buying a separate cord set. Mounting is pendant hanging or surface. You still supply whatever you hang it from, such as chain, aircraft cable or rod, and the junction box.

Each 65-783R2 puts out 20,850 lumens at 150 watts, which is in the same delivered-light territory as a 400W metal halide after that lamp's lumen depreciation, so a one-for-one swap on the existing layout is the usual approach. Verify your target footcandles and mounting height, since output per fixture is fixed here (no CCT or wattage selection on this model).

The fixture carries a wet location rating and is cULus listed, so moisture exposure is acceptable, but NUVO classifies it as an indoor fixture. Use it in damp or wet indoor spaces like wash bays, cooler areas and open parking structures under cover. Do not treat it as an outdoor area light.

It is dimmable, driven through the whip to a 0-10V style control as a dimmable LED high bay. Color temperature is fixed at 4000K, neutral white, with no field-selectable CCT switch, so every fixture on the job will match if you order the same model. CRI is 80.

No. This is an integrated LED high bay with no lamp base and no serviceable bulb, so there is nothing to relamp. Rated life is 50,000 hours, and at end of life you replace the whole fixture. For facilities that want to keep spares, stocking one complete unit per bank is the practical approach.

The body is die-cast aluminum, which doubles as the heat sink for the LED module. That is what you want in a shop, warehouse or mechanic bay where ambient heat and dust are a factor, versus a plastic-bodied fixture. Finish on this model is black.

The fixture is RoHS compliant, and NUVO lists lead as the California Proposition 65 chemical of concern, so a Prop 65 warning applies on California deliveries. Safety listing is cULus.
