NUVO Lighting 65-641R1 LED Adjustable High bay, 110W, 4000K, Integrated Sensor Port, 120-277V

One part covers both. The 65-641R1 is a universal-voltage driver rated 120V to 277V, so the same fixture works on 120, 208, 240 or 277 volt circuits. That is why it gets specified across mixed-voltage facilities where the shop floor is 277 and the back rooms are 120.

The fixture has an integrated sensor port built in, so a compatible sensor module can be added without modifying the housing. It is also dimmable, which is what makes daylight harvesting or a dimming control layer practical on the same fixture.

Damp location rated and listed for indoor use only. That covers an unheated warehouse, a parking structure interior, or a covered dock where condensation happens. It is not rated for direct spray or wet location, so a wash-down bay or an open exterior application needs a wet-rated fixture instead.

Fixed. The 65-641R1 is not CCT selectable, so it runs 4000K neutral white only. If you need to match 5000K fixtures elsewhere in the building, or you want field-selectable color on the same SKU, this is the wrong part and you want a CCT-selectable high bay instead.

Each 65-641R1 delivers 15,871 lumens at 110 watts, 4000K neutral white, with 80+ CRI. Spacing depends on mounting height and target footcandles, but that lumen figure per fixture is the number to run your layout from. It is a linear high bay measuring 26 inches long by 12 inches wide by 1.88 inches high, so it lays out along an aisle rather than as a round point source.

Safety listing is cULus, which covers both US and Canadian installations. The fixture is also RoHS compliant. Note the California Prop 65 disclosure on this item is for lead.

No lamp to replace. The LED array is integrated into the fixture, rated to an average 50,000 hours, so there is no socket, no bulb, and no relamping cycle to budget for. At end of life the fixture is replaced. For an MRO buyer that means a lamp SKU comes off your stock list entirely.

Mounting method is ceiling, and the fixture weighs 7.72 lbs, which is light enough for standard chain or aircraft-cable suspension as well as direct surface mount. The whip is 5.91 inches, so plan your junction box or power feed close to the fixture body. Housing is aluminum alloy.

White is the only finish offered on the 65-641R1. There is no bronze or aluminum option on this model, so if you are matching existing bronze fixtures in the space, the white housing will read differently.
