Great unit! 38 watts, not 372 as listed
I love this LED panel! Easy to install and wire, and tilt down to select one of three color temperatures. 3500 is perfect in my kitchen, but easy to change. The light is perfectly uniform across the whole 2 x 2 foot panel – amazing!Alarmed by the product info on this page (currently), I temporarily wired it through a watt meter and it’s only 38 watts. I knew 372 watts as listed could not be right, so I reported it to Amazon as inaccurate information and maybe it will be changed by the time you read this.

Light is much brighter than lumen rating
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.

Easy Install – Bright Light
I was replacing a fluorescent fixture in a large pantry. I had previously installed a similar, smaller LED light (that I bought from Costco) in a walk-in closet and was very happy with it. I read the reviews and was prepared to hang the fixture myself with the help of a neighbor.The package arrived in good condition (I live in Hawaii, so it was a long trip), and the instructions were pretty straightforward. I put a ladder in place, turned off the electricity to the old fixture, and installed the brace that supports the light myself. It came with all the hardware needed. The most difficult part was making sure the bracket was on straight.Then my neighbor joined me, and we hung the light. To be honest, he hung the light while I held it in place. It took about two minutes to snap it into the bracket. It mounted flush to the ceiling and looked great.Next, we turned the electricity back on, flipped the switch, and voila! the light came on bright and steady. That’s when we realized we had picked the wrong color temperature option. It looked like a standard blue fluorescent light, but I wanted a daylight color. So, up the ladder he went, easily unsnapped the fixture (while it was still on), and moved the switch to test out the other colors. I decide on the daylight option. Note that the Color temperature has three options – 3500K (Neutral), 4000K (Cool), and 5000K (Daylight).The light is much brighter than I thought it would be (but better than being too dim), so my next purchase will be a dimming switch. The fixture is advertised as dimmable; others have said there’s no hum, even when you dim.All in all, I’m extremely happy with my purchase, especially for the price. The ease of installation was a plus. I may edit my review after I install the dimmer switch.

As this was an open-box return, I received this product slightly damaged and partially assembled at a good discount from Amazon. Paper installation instructions were not included, but they do give you a QR code to scan. Once downloaded, I found the instructions to be clear and straightforward.Installing the bracket that holds the panel against the ceiling for flush mounting will be easy for most of you. For me, I never know what new adventure awaits me once I’m through the drywall of the century-old house I live in. In this case, it was some strange, flaky press board that will neither hold a wood screw nor allow the supplied toggle bolts pushed into it to expand–but that’s my cross to bear. The instructions and mounting kit for this product should work fine for those of you living in houses built to something post-dating the code of Hammurabi.I installed this in my kitchen. The light produced by this panel is beautifully even and quite a bit brighter than what I was getting from my old twin-fluorescent tube fixture. Because it’s so bright, I recommend installing it with a good dimmer switch.The ability to adjust the colour temperature of the light to one of three shades is also really nice.
