NUVO Lighting 65-833R1 4 Foot, LED Tri-Proof Linear Fixture with Integrated Microwave Sensor, CCT & Wattage Selectable, IP65 and IK08 Rated, 120V-347V

The 65-833R1 is an outdoor-rated fixture with a Wet location rating and an IP65 and IK08 rating, so it handles direct water spray and takes an impact hit. That combination is what puts these in parking garages, wash bays, car washes, food processing areas and unheated warehouses. The housing is plastic, so there is no steel body to rust out in a damp space.

Wattage is field selectable at 40W, 50W or 60W, and color temperature is selectable on the fixture as well. Output runs 5040 to 7669 lumens across those settings, at 80 CRI. Practically, you pick the low step for a corridor or covered walkway and the top step for a garage drive aisle or a high-bay-adjacent storage run, and you do it at install instead of ordering three different part numbers.

The body measures 47.24 inches long, 3.98 inches wide and 3.11 inches high, so it is slimmer and shallower than a typical 4 foot fluorescent vapor tight with a wraparound acrylic lens and drops into the same 4 foot run. It weighs 4.63 pounds, which matters if you are hanging it from an existing chain or aircraft cable set rather than surface mounting.

The fixture carries a cETLus safety listing, which covers both US and Canadian requirements and pairs with the 347V top of its voltage range for Canadian work. It is also RoHS compliant. One thing to flag for spec writers: it carries a California Prop 65 notice for lead.

The sensor is integrated into the fixture, not an add-on, and it is a microwave (RF motion) type rather than passive infrared. Microwave sensing sees motion through the lens and works in cold and dirty spaces where PIR struggles, which is why it shows up on a sealed tri-proof body. Nothing in the fixture data sets out the sensor's adjustment range, so plan the layout around a fixture that senses motion on its own rather than around a specific time delay or sensitivity step.

Both. The fixture is rated for wall and ceiling mounting, so it works surface mounted overhead in a garage or stairwell and mounted flat on a wall in a tunnel, ramp or equipment room. The plastic body keeps the hanging weight down at 4.63 pounds.

Yes, the 65-833R1 is dimmable. Bear in mind it also carries its own integrated microwave occupancy sensor, so in a space already running a central control system you are layering two controls on the same fixture. In garages and storage runs that is usually what you want: the sensor drives occupancy, the dimming sets the standby level.

No lamp to replace. The LEDs are integrated into the fixture, rated 50,000 hours average, and there is no socket or tube. At end of life you change the fixture, not a bulb. For an MRO buyer that removes the fluorescent tube and ballast line item from the stockroom entirely, which is usually the point of moving a garage or wash bay over to tri-proof.

Use the tri-proof where the fixture is exposed to water, dust or a stray impact. A standard open strip light has no sealed lens and no impact rating, so in a garage, wash bay or covered loading dock it collects moisture and grime and gets clipped by a ladder or a truck mirror. The 65-833R1 is sealed to IP65 and impact rated IK08, wet location listed, in a plastic body. In a clean, dry, conditioned space like an office storage room, a plain strip costs less to install and does the same job.

It comes one way, in a white and gray finish, which is the usual utility look for a sealed linear fixture. There is no alternate finish to specify, so the order is just the one part number, 65-833R1.
