Lithonia Lighting 2x2 LED Flat Panel Light, 3300 Lumens, 3500K/4000K/5000K

I had a 2-U fluorescent fixture in the kitchen that either had burned out bulbs or a bad ballast. Instead of troubleshooting that I chose to simply replace the whole thing with LED. Many would punch holes in their building's envelope by putting a bunch of can lights, but I'm happy with the light produced by the fluorescent so don't need to leak all my heat into the attic. Pros: - Relatively easy to install. The entire removal and installation took me about an hour but I have zero practice. Subsequent fixtures would take less probably 30m each. I did it alone even though instructions recommend two people. As the light hangs from its bracket at 40 degree angle on hanger cables (not the power cable) there is no awkward part of the process where another person would significantly help. The tedious part is marking spots for 1/2" holes for butterfly bolts such that the fixture will hang square to the room. Its no worse than installing a fluorescent. - Its rated at 3300 lumens. 2* 40W U tube is 4600-5400 lumens depending on brand. My hesitation on ordering this was whether it would be dim. As i'm no spring chicken, I'd rather have the same or brighter. This fixture is comparable to the 2-U with the diffuser removed. Its much brighter than the 2-U with the diffuser installed. If replacing a 2-U 40W (80W total) especially with a frosted diffuser, don't hesitate its not too dim! I suspect the bulbs are tested for lumens alone, but the LED fixture is tested for lumens as a complete product so the losses through the diffuser are accounted in the 3300 lumens. - Color temperature can be set to 3500K, 4000K, or 5000K. On this fixture the 3500K is close approximation of halogen, the 4000K is close to regular fluorescent tubes, and 5000K is blue. In order to get a better feel for the color climb off the ladder (while its hanging at 40 degrees on support cables) and discuss with your partner, because I found it difficult to unlatch and lower once fully installed. Cons: - One defect: a bright spot where the diffuser may have been creased in shipping. I chose not to return it with the defect as all the LEDs seem to be on, and the plastic isn't fractured. - There is a small 0.25" gap between the ceiling and the top of the light due to the way the bracket works. No light escapes through this gap (some brands seem to leak light up there). There are some brands whose bracket is a box to remedy this, but I don't find it a big problem especially on a 12 ft ceiling. It would probably be annoying on a 7 or 8 ft ceiling like a basement. - The light takes half a second to turn on. Its faster than the fluorescent, but there is a slight delay between flipping the switch and the light coming on (at full power). The light claims to be dimmable with a regular (triac) dimmer. If I decide I don't like the brightness (too bright) I'll install one and update with how well it dims. It claims 60000 hour life and 37W consumption (little more than 1/3 the 96 watts for 2*U 40W plus ballast). It should outlast me as LED's don't suffer much from repeated switching. I'll be mildy annoyed if it fails early, and majorly annoyed if it fails when I'm too old to replace it myself (and have to pay someone a huge amount to swap it). Update: decided it was too harsh/jarring to turn on at 0430. Installed a Lutron AYCL-153P-WH. The CPANL dims very linearly and nicely down to a slight glow. When turned on dimmed the delay from switch on to light produced increases. There is no flicker or buzzing noises from the light or dimmer. About half power is good to avoid getting jarred awake, and its nice to have the full brightness available when needed.

Purchased for the pantry to replace a fluorescent T8 fixture. Old light was a three-bulb (30w each) bright white 3000k unit. I purchased the 2x2 and set it at middle (4k) setting. Extremely comfortable light and every nook and cranny can be seen now. There were no installation instructions, instead you use a Q code to get them online. But if you have any knack at all, the whole assembly is just common sense. Hold a lightweight bracket to the ceiling, mark 4 spots for screws, drill 1/2” holes so butterfly anchors can be inserted, put the screws and anchors on the bracket and mount on the ceiling. Or, if you have an acoustic ceiling with a metal grid and tiles, just swap out a tile for the light. The light itself simply snaps and locks into the bracket (and has safety wires so it won’t fall accidentally or in an earthquake 😎All in all a good upgrade. Less energy, low profile and lots of light. It stands off from the ceiling about 3/8th of an inch. In new construction I suppose you could recess a shade, or simply glue trim to hide the gap. But my wife said, “I like that this one sits flush to the ceiling.” So I think it is unnoticeable at a glance.

Excellent light fixture easy to install I bought over a hundred and had no problems at all will buy them again

I ordered three of these lights. They were sent promptly. One was damaged in shipping and is being replaced. The two surviving lights are perfect. We like the sleek fixture and ability to choose the Kelvin Rating of the light between three levels from warm to cold. The light output is bright. Installation was relatively easy for me as I do most home repairs.

I am very happy with this light! It has a modern, slim line design and really lights up the kitchen. It was easy for my handyman to install. No complaints and would recommend.

Easy to install, looks great, and produce diffused bright light.

These worked great in my basement. Easy to assemble and are very bright.

Nothing lines up. Don’t waste your money. Light is good. The template to attach to the ceiling lined up but, no give or take on the dimensions. I can’t slide the light portion up onto the template to attach the light to the ceiling. Very frustrating. I bought a simpler circular led light. Easier to install. I’m an Engineer. Not returning it, but not buying it again.

Product was easy to install. Used in walkin closet .
