Lithonia Lighting CPANL 2×4 LED Flat Panel Light, 2 ft. by 4 ft. LED Light Panel, Ceiling Lighting Fixture, 4000 Lumens, 3500K/4000K/5000K Switchable CCT, Includes Direct Ceiling Mount Bracket, White

Easy install, great unit
The laundry room luminaire started flickering again; great, another pair of 48″ fluorescent tubes to recycle.Nope. Rather than continue the cycle I decided to replace the entire unit with this Lithonia CPANL LED luminaire.Installation was a breeze. It took a lot longer to remove the original luminaire and its ballast than to install this new one. A solid 75% of my time was spent just removing the old fixture.Thanks to the unit emerging from its packaging almost 90% assembled (thank you!) all I really needed to do was take a few measurements and hold the mount up against the ceiling to mark the spots for drilling. Drill. Thread the bolts through the mount into the toggle bolts, shove the toggles into the holes, pop through, tighten; this is all typical simple DIY electrical stuff.Then, the panel just hooks on one side of the mount, and latch-locks the other. Super-easy to “open and close” it and security tethers hold it gently in place while you’re wiring it. If you want to change the color temperature, you’ll need to open the latches and drop the unit to access the switch, so easy off/on is a pretty nice feature to have. This one’s done well. Electricals are exactly what you’d expect, wire nuts, black to black, white to white, green/unsheathed to ground. Four metal toggle bolts hold the mount and luminaire to the ceiling.Bright and beautiful; it’s roughly 50% brighter than the fluorescent unit it replaced, and at one-quarter the wattage.Oh, and it’ll likely outlive me. Not that I’m planning on kicking off any time soon but at an hour a day of use this unit has a 100-year projected life span and I’m just not planning on living QUITE that long. No more tubes to specialty-recycle!Some helpful tips here. You’ll need a few tools, but nothing any basic DIY’er wouldn’t already own. And if you don’t own them, this is your opportunity to purchase them because you’ll use them for a hundred future tasks anyway, also known as “Honey, see, I need them because this guy in this review says I do.” Your mileage may vary as may the impending status of your relationship; I have no experience as a therapist and as such this is not a counseling offer and I make no warranties express or implied that this sort of manipulation will produce the desired results. It may be fun to witness nonetheless.But in all seriousness:You’ll need a 1/2″ drill bit and some kind of power drill. Eye and basic face mask (hey, you’ve got all those leftover N95’s right?) are appropriate; you’re drilling the ceiling.Good: Medium flat blade and Philips screwdrivers. Better: flat/Philips bits for that power drillFlatnose/Lineman’s Pliers. Most national codes require a pretty good twist a good bit up the insulation to hold the wires firmly before you cap them. Don’t cut corners; your fingers won’t work here.One note: SAVE THE STRAIN RELIEF from your original luminaire. This is that little plastic spacer that the wires go through, to protect them from being cut by…the razor-sharp metal holes the wires thread through on this unit. Despite the manual stating to use one, they DID NOT INCLUDE that strain relief part in the box. Thankfully, the 30+ year-old one from the removed unit fit perfectly so I didn’t even need to source one and they seem to be fairly standard.All in all, great unit, zero installation issues, works perfectly.

A Professional’s Take on the Lithonia CPANL 2×4
As a licensed electrician, I’ve installed countless light fixtures, and the Lithonia Lighting CPANL 2×4 is one of the more solid LED panels I’ve encountered. This isn’t just a simple light; it’s a professional-grade solution that delivers on its promises, particularly for commercial or workshop applications.The installation process is what sets this unit apart. The fixture is lightweight, which is a major plus when working overhead. It comes with a direct ceiling mount kit, and while some online reviews have noted a flimsy bracket, I found that when secured properly with all four anchor points, it provides a stable and reliable mounting platform. The hinged design is a clever feature, allowing you to hang the panel for hands-free wiring. My only minor gripe is that the pre-stripped wires could be a little longer to make connections in the junction box easier. The ability to switch between 120V and 277V is a huge convenience for a contractor, giving it a versatility that’s perfect for both residential and light commercial jobs.In terms of performance, the CPANL is impressive. The adjustable lumen output (ALO) is a fantastic feature, allowing you to select between 4,000, 5,000, and 6,000 lumens. This is excellent for tailoring the light level to a specific room, whether it’s a bright workshop or a more subdued office. The selectable color temperature (SWW) is equally useful, giving you a choice of 3500K, 4000K, or 5000K to match existing lighting or the client’s preference. The light output is smooth and consistent, with no noticeable glare or hot spots. The 80 CRI is standard for this class and provides good color rendition for most applications.The build quality is what you’d expect from a reputable manufacturer like Lithonia. The aluminum frame feels durable, and the sealed design prevents light leak. The integrated LED design means there’s no need to worry about bulb replacements, and with an L70 rating of 60,000 hours, it’s a fixture that will last a long time. Overall, for its ease of installation, adaptability, and high-quality light output, this is a product I would confidently recommend to other professionals and use on future projects. It’s a reliable workhorse.

Super product at a super price
This light is perfect. It’s nearly flat to the ceiling, and with a few easy steps it went in seamlessly.It’s so nice and bright! It also has a dimmer if brightness needs to be adjusted.Great option for the price.

This is exactly what I wanted. However, in spite of what the ad says, it isn’t dimmable. It flickered and would alternate between bright white and warm white. I took the dimmer off and it works perfectly. It is a dimmer rated for LED units so not sure why. But the fixture and lighting options are great.

Purchased for my food truck.Multiple lighting option, quick instalation, space saver since head space in food truck is limited. Perfect, have now for approx a year, no issues.
