The 2 ft. x 4 ft. LED Lay-in Troffer from Lithonia Lighting represents the best quality general purpose LED lighting available in the industry.

  • Multi-volt (120 - 277-volt) LED driver, delivers full-range dimming down to 10% with a 0 - 10-volt dimmer
  • Standard extruded aluminum door frame has superior structural integrity and mitered corners for a premium appearance, and rotary cam latches provide easy, secure door closure
  • Easy, lay-in installation in 2 ft. x 4 ft. grid ceilings with integral T-bar clips
  • CSA listed for damp locations
  • With a 50,000-hour service life (twice that of fluorescents), this fixture can easily last more than a decade before requiring replacement
  • Smooth hemmed sides and smooth inward-formed end flanges, for easy handling during installation
  • 0.040 thick frosted white acrylic diffuser distributes light evenly for improved visual appearance

Rated 4.5 out of 5 by 23 reviewers.
Rated 5.0 out of 5.0 by 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. July 21, 2015
Rated 5.0 out of 5.0 by 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! September 17, 2013
Rated 5.0 out of 5.0 by 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! August 12, 2014
Rated 4.0 out of 5.0 by Great Workshop Light I purchased this for a 12' by 12' work shop area. based on my experrience with its traditional equivelant i expected to use two or three of these to get my desired amount pf light. This single unit fills the room with nice even bright but not harsh light. Perfect for projecting. Installation eas a breeze even with barely enough clearance over the hung cieling. Looks great and once it is on its silent and provides a perfect light. I am a little dissapointed with the slight delay before it turns on however given the amount of light output vs power consumed, combined with the fact that it is a work shop. Im tickled pink. I am also elated that i wont have to keep a stock of replacement tubes nor have to deal with disposing of old burnt out bulbs. That alone is worth the slight price increase. February 12, 2015
Rated 5.0 out of 5.0 by Great Product The light really fit the bill. It was easy to install and already had the bulbs installed and ready to go. Just wire and power on. The LED lighting has superior color quality and really lit up the work area. November 4, 2014
Rated 4.0 out of 5.0 by 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! June 17, 2014
Rated 5.0 out of 5.0 by This light is super bright ! Love it ! Led is a great way to save electricity ! Love the fact you don't know it is led and looks like fluorescent ! It is brighter than a 4 tube fluorescent fixture ! April 23, 2013
Rated 4.0 out of 5.0 by works well Purchased two of these a few weeks ago for a 200 square foot office. Plenty of light with good distribution. It does take a half second for the driver to power the lights once the switch is turned on. Easy installation with push connectors. January 13, 2015
