NUVO Lighting 65-577 LED Emergency Backlit Flat Panel, 40W, 1ft x 4ft, Selectable CCT, 100-277V

Yes. The 65-577 measures 47.72 inches long by 11.84 inches wide by 1.5 inches deep, which is sized for a nominal 1 ft x 4 ft grid opening. The 1.5 inch depth is the number to check against your plenum, and at 4.98 lbs it is light enough to lay into a standard T-bar grid. It's a ceiling-mount fixture.

Emergency operation is built into the 65-577 panel itself, so the same fixture serving general illumination also carries the egress light when normal power drops. That means you don't need a separate battery pack fixture at that location for the panel's own emergency output. It does not replace an exit sign, which is a separate device.

Yes. The 65-577 is a universal-voltage fixture rated 100V to 277V, so the same part number wires to 120V tenant circuits and 277V commercial lighting circuits. That's useful when you're standardizing one SKU across a mixed-voltage property instead of stocking two.

Color temperature is field selectable on the fixture, so you order one part number and set the CCT at install. That lets you match existing panels in a corridor or suite without ordering a specific Kelvin version. Output lands in the 4400 to 4600 lumen range at 40 watts with 80+ CRI.

No, not outdoors. The 65-577 is an indoor fixture with a damp location rating, so it handles humidity in areas like restrooms, covered corridors, and kitchens, but it is not wet-location rated and should not be used where it will see direct water or weather exposure.

It is cETLus listed, which covers both US and Canadian requirements, and the fixture is also RoHS compliant. Note the California Prop 65 disclosure for lead if you are shipping into California.

The 65-577 is a dimmable fixture, so it can be put on a dimming control leg rather than switched only. Confirm your driver control type against the wiring label at install, since dimming is the stated capability here.

The LED board is integrated, so there is no lamp to change out. Rated life is 50,000 hours; when the array reaches end of life you replace the fixture, not a bulb. Budget maintenance accordingly if you are spec'ing a fleet of these.

The fixture's wire length is 3.54 inches, so it's a short lead, not a long flexible whip. Plan on a junction box close to the fixture or a splice enclosure right at the housing; if your box sits away from the panel you'll need to run fixture whip to reach it.

Backlit means the LEDs sit across the back of the panel and shine through the diffuser, which generally gives a more even wash and lets the fixture be built thinner on the light-guide side. Edge-lit panels fire LEDs from the perimeter into a light guide plate. For a 1x4 grid replacement in commercial space at 40W and roughly 4400 to 4600 lumens, this backlit panel is the straightforward general-illumination choice, with the added emergency function built in.

Housing is aluminum and steel, finished in white, which is the single finish offered. It's a utility-style panel, so it's intended for corridors, offices, back-of-house and similar commercial spaces rather than decorative applications.
