Customer Questions & Answers

Can these be mounted to the ceiling?

I don't have drop in ceilings and was wonder if I could mount these fixtures to the ceiling? These are the ones I currently have that I would be replacing.
Asked by: Caitlin
No. This fixture is designed to be installed into a metal grid system.

Do these units come with a ballast? If not which one is needed?

I recently picked one up and the wiring connectors are unfamiliar to me. Specifically there are 2 connectors (cable colors gray and purple) that would appear to be for a ballast, but none were in the box. A photo is attached (I can tell the black/white connector is for the line voltage). Lithonia's web site is not helpful at all. Thanks!
Asked by: Dave
No ballast with this LED fixture. Just connect the ground wire to the installation plate, and than take beige plastic connector, strip back !/2 inch on white and black wires that come from your power source and shove them straight into the connector holes marked "black" and "white" until they click in all the way and you can't pull them out. Then click the beige connector together and you are done. Don't mess with any of the other wires. It is so simple that it seems like you should be doing more, but that is it! The connectors that you are seeing just connect the ends of the LED strips to each other. Leave them alone.

Is this an easy changeover from a stndard fluorescent fixture for one person?

Asked by: Anonymous
Yes. I am a 66 year old female and I did it by myself. I would suggest that after you shut down the power to the fluorescent light fixture, remove the bulbs, the lens cover, and the metal covering over the ballast. Then you can cut the wires and pull out the ballast(s). This reduces much of the weight of the old fixture and makes it easier to get down, particularly if you are on a ladder. The LED fixture does not contain a ballast, so it much lighter in weight to install.

Rated 5 out of 5 by from No issues with product only issue is with shipper - product was shipped to us damaged and with broken lens cover No issues with product only issue is with shipper - product was shipped to us damaged and with broken lens. All four corners were bent and scratched. Love the product didn't like the delivery!

Rated 5 out of 5 by from Looks great! We purchased 10 so far, another 40 to go! Our building is 35 years old and we have been waiting for the price on LED to drop where it makes sense (and cents) to replace our old failing florescent fixtures. They are made of thin flimsy sheet metal but once you straighten the corners from shipping and install they look awesome! The light output is bright and the perfect balance - not at all bluish white and not to soft white. Well worth the price. I recommend you buy them!

Rated 4 out of 5 by from Great for the price Super bright! Easy to install, they are light weight, and a bit flimsy, but look great once in place. Most were bent around the edges, but once in the drop ceiling you could not see it. The box was not damaged so they were shipped from the Manufacture that way! Otherwise Great value and Home Depot had the best price for them!

Rated 5 out of 5 by from Love the quality and light these provide. Not too bright & the right "color". Advertised as low energy use. I already like the difference in the quality of the light emitted in comparison to the old fluorescents. It's not like the typical LED that's so bright and blueish. The light is warmer and more white.

Rated 5 out of 5 by from Good product, works well, bright This troffer fit right into the space where I took out an old fluorescent fixture. Connect a couple of wires with wire nuts and slip it into place. Seems like decent quality and gives off a plenty of light. About a 1 second delay to turn on... not an issue except the first time you do it to see if you have successfully installed it and you are about to curse because you think you messed up. When it does come on after a second, it is instantly bright.

Rated 4 out of 5 by from This is very energy efficient The lithonia fixture looks exactly like the traditional fluorescent troffers. They are not as bright as the envirolite fixtures from Home Depot and don't distribute light as nice either but they work great and use less watts .

Rated 5 out of 5 by from Insanely Bright One of our employees needed a light fixture over his cubicle. It's a large area with about 25 cubicles and for some reason his didn't have enough light. The rest of the area has T-8, 3 bulb 2' X4' fixtures spaced pretty evenly. I installed this fixture with ease in about 10 minutes. It fit perfectly in the dropped ceiling grid and was easy to wire-in with a 10' whip. When it came on it was insanely bright, I will probably have to purchase a 0-10 volt dimmer. The employee is using SPF-50 until I get the dimmer(just kidding).
