NUVO Lighting 65-646R1 LED Adjustable High bay, 165W, 5000K, Integrated Sensor Port, 120-277V

Yes. The 65-646R1 linear high bay accepts any input from 120V through 277V, so it drops onto 120, 208, 240 or 277 volt circuits without a separate driver or a voltage-specific part number. That universal range is what makes it practical to standardize one fixture across a building with mixed panel voltages.

No. It is rated for indoor, damp locations only, which covers a covered loading dock, an unconditioned warehouse or a garage interior, but not wet locations or direct weather exposure. For open-air or spray-down areas you need a wet-location-rated fixture instead.

The 65-646R1 has an integrated sensor port built into the housing, which is the receptacle a compatible occupancy or daylight sensor plugs into so the fixture can switch or dim on its own. The fixture itself is dimmable. The port is what is supplied; plan on ordering the sensor module separately as part of your controls package.

A linear fixture like this 26 by 12 inch NUVO spreads light along its length, which suits rack aisles, assembly lines and long narrow bays where you want the beam running with the aisle rather than a circular pool under each point. Round UFO high bays concentrate output in a symmetrical pattern and fit open floor areas better. This one is also adjustable, so the light bars can be angled to throw across rack faces instead of straight down.

No. The LEDs are integrated into the fixture, 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 the whole fixture gets swapped. For MRO planning that means a fixture-level replacement line, not a lamp stock item.

It carries a cULus safety listing, which covers both US and Canadian installations, and it is RoHS compliant. The housing is aluminum alloy. Note the California Prop 65 disclosure for lead, which applies to shipments into California.

Yes, the 165W high bay is dimmable, so it can be tied into a dimming control scheme rather than being switched only. Combined with the integrated sensor port, that lets you run occupancy-based high/low levels in a warehouse or gym instead of full on/off cycling.

White is the only finish for the 65-646R1. Ordering is straightforward as a result: the part number 65/646R1 covers it, with no finish or color temperature suffix to specify.
