Customer Questions & Answers

Is this 3000K, 4,000K, or what in color?

Really would like to know what color light these LEDs produce. Thank you in advance for your answer.
Asked by: John
Lithonia's spec says 3500K, CRI 82, 4800 lumens, and subjectively it looks pretty much like that. (You can buy a 4000K version, and it'll show in the model number.)

How many lumens does this light produce?

How many lumens?
Asked by: Anonymous
4762.8 Lumens is listed in the description. A single 48" T12 florescent bulb (new) is about 2500 lumens, so this is roughly the output of two 48" bulbs, which would be just right for my kitchen without a dimmer.

The Hampton lights have a problem with the ballasts you never want to buy those i have to replace two of mine and i want to make sure these are free of ballast or any other known problems.

4 ft. LED Volumetric Wraparound Surface Mount Ceiling Light is rated 4.7 out of 5 by 9.
Rated 5 out of 5 by from Fluorescent-like lighting from LEDs Ample light. Well designed for ease of installation. I replaced a failing twin-tube T12 Fluorescent light in an 11' x 6' walk-in closet with this unit. Definitely outperforms T12 and competitive with T8 illumination. The price was a bit discouraging, but I am satisfied that I have gotten my money's worth.

Rated 5 out of 5 by from This product is better than expected! This LED light is a terrific alternative to 4 ft multiple bulb fluorescent fixtures. The light is warm like an incandescent bulb and provides a lot of light. The fixture can be used with a dimmer. I plan to use this model fixture in other rooms

Rated 4 out of 5 by from fine fixture, but maybe "feeling inadequate" about its length... 1) This "four foot" fixture is not 48" long! It's 46 1/2" (to 46 5/8" if bends aren't perfect). Thus if you're replacing an existing fluorescent fixture, you'll have to drill new mounting holes; these are approx. 42 1/2" apart instead of the typical 45". 2) The NX model has a 0-10-volt dimming ballast/driver installed. The box says "dimmable" but I didn't try using either an LED-compatible dimmer on the AC line or a 0-10V dimmer on the DC control I/O. In other words, I didn't connect the extra cables and it runs at 100% just fine, on a plain old light switch. 3) If you've never seen "WAGO 873" style wire-nut connectors before, they are push-in. Just strip 1/2", or maybe a hair less. (Copper only, no Cu-Al.) 4) The diffuser has a frosted film laid inside the usual striated plastic, to further hide the individual light point-sources. So you can't do any "creative" mounting on a side wall because it'll sag over time; this is a ceiling light and you must use it that way. 5) The LEDs are not dispersed 100% all the way to the very ends of the fixture, so you'll have a less-bright stripe at the ends, just like in a fluorescent fixture! Bummer... 6) Check your fixture before accepting it; particularly tilt the box end-to-end, to listen for any rattle. The diffuser is shipped pre-mounted on its end pins -- so if they drop the box, the heavy metal frame & ballast will hit the stops/hanging clips at the ends of the diffuser and might break off one or more. Broken end-clips means you'll keep over-shooting when trying to click the diffuser in and have to pull it back down. Basically the light seems just fine, but it's only a minor improvement over an existing T12 fixture. That is, over a new fixture with *brand-new bulbs* -- but with this one, you won't have to keep replacing tubes as they dim, nor the ballast when it ages! Lithonia's spec sheet now claims this will stay at 90% of initial lumens for 60,000 hours(!), not the L80/50,000 listed here. It does look roughly 3500K and 4800l as claimed, at least in the middle. Light output falls off beyond the end caps, but the sides shine pretty well, only a tiny bit more "volumetric" (as claimed), than a standard fixture.

Rated 5 out of 5 by from Let there be light! The brightness is not quite the same a 4-tube fluorescent fixture, but the color of light is much nicer. Especially in a kitchen. As an added bonus, there is no buzz from an angry ballast. If you are thinking about buying one, just do it. The instructions are easy to understand and the installation is a breeze.

Rated 4 out of 5 by from Nice dimmable light Good light and great range when using the 0-10v dimmer. Does require extra wiring to the fixture but it is worth it. A couple lenses broke on shipping. Hopefully it will be easy to replace
