NUVO Lighting 65-1143 LED 4ft, Wide Strip Light, 40W, 5000K, White Finish, with Knockout and Sensor

Yes. The 65-1143 4 ft strip light accepts 120V through 277V, so it drops onto either a standard 120V branch circuit or a 277V commercial lighting circuit without a separate model or ballast change. That makes it workable for warehouse, back-of-house, and parking structure interiors fed at 277V as well as residential-style 120V garages and basements.

It is rated for damp locations and listed for indoor use only. A covered, unheated space where it may see humidity or condensation is fine. Direct water spray or any exposure to rain is not, so a car wash bay or an open exterior soffit needs a wet-location fixture instead.

Yes, the 65-1143 ships with an integrated sensor, so it switches on its own without a separate wall-mounted occupancy control. Property managers using these in stairwells, storage rooms, and back corridors get the energy-code control built into the fixture rather than wired separately at the switch leg.

Each fixture delivers 4,909 lumens at 40W in 5000K daylight white, with 80 CRI. For general shop, storage, and utility spaces that is a one-for-one replacement for a typical two-lamp or four-lamp T8 strip. Row spacing comes down to ceiling height and target footcandles, but at roughly 4,900 lumens per 4 ft unit most MRO crews lay them out on continuous or near-continuous runs down an aisle.

Dimmable, yes. Color temperature is fixed at 5000K, not field selectable, so if you need 3500K or 4000K to match adjacent fixtures this is the wrong unit. Buy it when daylight white is what the spec calls for across the whole space.

Both. The fixture is listed for ceiling or wall mounting, and it has a knockout for conduit or cable entry, so it surface mounts directly to a deck, joist, or masonry wall and takes a feed straight into the housing. No separate junction box is needed at the fixture if you land the feed through the knockout.

No. The LED is integrated into the 65-1143, so there is no lamp or socket to service and nothing to stock as a spare. It is rated to 50,000 average hours, which is why facilities crews use these to get fluorescent relamping off the PM schedule entirely. When the fixture reaches end of life the whole unit is replaced.

It is RoHS compliant, and it carries a California Proposition 65 warning for lead. Institutional and government buyers who track both on submittals should note the two together: RoHS yes, Prop 65 lead listed.

NUVO Lighting part number 65-1143, also printed as 65/1143. It is the 4 ft wide-body strip, 40W, 5000K, white finish, with knockout and sensor. White is the only finish this configuration is built in.
