Lithonia Lighting 4 Foot LED Light Fixture, Low-Profile LED Wraparound Flush Mount Ceiling Light, 4000K Cool White, 120V, 48-Inch (FMLWL 48 840)

Great light fixture.
I purchased the 24″ 300K light. It is very light weight and looks great. The light color is just about perfect in warmth compared to the cold flourescent light I replaced with it. What I think you should know is how this mounts. This is perhaps my first time installing a flush mount light fixture. I replaced a 2-bulb failed flourescent light fixture of the same length in our laundry/mud room. When I removed the old fixture, I discovered they had mounted it using anchors in the drywall ceiling, and the romex wire was just coming through a hole in the drywall as well. I don’t like that idea, so I installed a shallow depth 4″ round electrical box to contain the wiring and wire connections. I used the screws that came with that box to mount the new light fixture. This is where it got interesting. The romex wire coming through the ceiling was stapled right to a stud there so I cut out the drywall to fit the 4″ box and aligned the box mounting holes along the centerline of the ceiling stud. But, when I mounted the light, it was crooked on the ceiling because it is made to install onto the screws, then twist so the pan head screws hold the fixture and you then tighten the screws down. Trying to get the electrical box aligned so that the light fixture would be mounted straight on the ceiling after that twist action was quite a feat, one I wouldn’t like to repeat. That’s not the fault of the light fixture but I’m not sure how you could mount it straight if your existing electrical box screw holes aren’t aligned the way this fixture is designed. Hope that makes sense.Outside that nasty adventure, this light looks fantastic! It is bright, warm and best of all, dead silent.

Good light, but industrial aesthetic, and only an average value (see details). Recommended
The issue that I was dealing with, was that the 4′ fluorescent fixtures in my primary bedroom closets were having bulb and/or ballast issues. Why not replace the fixtures with something more efficient anyway? I was already familiar with Lithonia Lighting, as I’ve purchased some of their lighting products in the past, so it seemed like the Lithonia Lighting FMLWL 48 840 LED Flush Mount Wraparound Light (4-Foot, 4000k, Bright White) would be a decent choice.When I was taking down the old light fixtures, I noticed an issue… no J-boxes. Instead, Romex was poking through a hole in the sheetrock. Ugh. At least a ground wire was coming through, too, though it’s a bad thing when that’s the kind of thing that makes you happy. Did I mention that I was wall-mounting these? Because the Romex was coming through holes drilled in the framing over the closet door, there wasn’t a quick or easy way to add a J-box in the same spot. I opted instead to go with a flush mount. There’s a small, circular knock-out on the back of the light fixture, so I cut a grommet for that hole, pulled the white/black/green fixture wires back into the housing, and hooked everything up. It works, but there are issues. It appears that Lithonia Lighting just took an existing fluorescent housing, glued in a DC power adapter, and put in a 5050 light strip. Theoretically this makes this light easy to repair or modify, if that’s your thing. Aside from the massive amount of wasted space, and shockingly high BOM cost vs. retail price markup, the location of the light strip makes it difficult to hide the wiring in a non-traditional installation like mine. Everything is downlight from the strip. Is that Lithonia Lighting’s problem? Maybe not, but it’s logical to assume that you might be able to use that massive housing for something.As far as the light goes, it’s pretty good for the 8’x8′ closets. Decent CRI, brightness, and diffusion (you don’t see distinct hotspots where the surface-mount LEDs are). Aesthetically, you could best describe these as industrially functional. The housings look cheap, but the diffuser looks pretty good. I’m a little torn when it comes to the VALUE of these fixtures. On the one hand, ~$50 per fixture isn’t bad… and I do expect them to last for several years. On the other hand, these seem pretty expensive for what you get. Recommended

Great fixture
This light is very bright. I am very happy with it because it is installed above my kitchen sink and the fixture it replaced did not put off as much light as this fixture.

great LED lighting!
very good led lighting for a garage area! (20×20), easy installation and straight forward! decided to use toggle bolts for the mounting of the light fixtures (very secure!) along with electric ceiling gang boxes on a 14/2 circuit. the fixturesare light weight and inside is the led driver (hot, neutral, ground wires). the lighting is 4000k, 3000 lumens (one led strip-centered) and is probably rated at 50,000 hrs. perfect for our needs and we are very satisfied customers!thank you! (note: purchased three of them)

The moment I turned on the power the driver for this light exploded internally. I hooked it up to 120v AC at 60Hz as it is intended to be.

Have had this lights for a while now. Easy to install and provides strong light for my garage! A little pricey for the quality of product but a decent value.
