2x2 2×4 LED Troffer Light

[Size: 2×4 2PACK]
I installed this two-pack of LANGGAN 2x4 LED troffer lights because I wanted bright, even lighting without turning the ceiling into a collection of mismatched fixtures. These are made for drop ceilings and have the clean, flat appearance I expect from commercial lighting. At up to 7,500 lumens, there is certainly no shortage of usable light. My dim old space got the message immediately.As I do with every product I review, I installed the fixtures, placed them in their intended locations, tested the settings, and used them normally rather than judging them after flipping the switch twice. Installation was reasonably straightforward if you're already comfortable working with this type of commercial fixture and electrical wiring. The 2x4 size fit the intended ceiling layout properly, and the finished installation looks neat. Electrical work isn't the place for improvisational comedy, so anyone unfamiliar with proper wiring should have a qualified person handle installation.The selectable color temperatures are one of the features I appreciate most. Being able to choose from 3000K through 5000K means I can go warmer or cooler depending on the room instead of discovering after installation that I bought the wrong color temperature. Selectable wattage from 25W through 50W provides another useful way to control how much light and power the fixtures deliver. The 0-10V dimming capability adds even more flexibility when connected to compatible controls.Light output is strong and spreads nicely across the area instead of creating a few painfully bright spots surrounded by gloom. I like having both wattage and color temperature choices because commercial spaces don't all need to resemble an operating room at noon. The ETL and DLC listings are also reassuring specifications for fixtures intended for offices, schools, hospitals, and similar environments. Overall, these provide plenty of illumination, useful adjustment options, and a professional-looking finished installation without making the ceiling the most complicated part of the building. Great value for the price and quality! ✅

First, the packaging could be improved. One of my units was dented, the box had 2-3 holes/flaps in it, just not good overall.Got these lights to replace the old tube style ones. Not sure why but when I tried to put it in the drop ceiling, it wasn't working out so haven't installed them yet.I did hook them up and hook up a pot to test the dimming. Works similar to Meanwell LED drivers.I really like that this unit allows you to pick your preferred CCT instead of being cool white like my old tubes. For my drop ceiling living room, the white was terrible. In my attic office, which currently uses one of those U shaped tube fluorescent bulbs, I hope to use one of these units to replace the existing fixtures.Overall, I think these will look good once they're finally installed. Also very much so like that they are LEDs and, in theory, should last a while.

My husband recently remodeled our garage in order to work on his many projects. At work they have the common troffer recessed light ceiling, and he wanted that kind of modern, sophisticated LED light where he could control the light color temperature and dimming.We got this two-pack of 2' x 4' troffer LED lights. 2 x4 is a standard size. They come in smaller sizes also, like 2 x 2, but he wanted this size. Nowadays troffer lights use LED lights like these, not the fluorescent lights of old.They were quite heavy (the shipping package was 32 lbs) and we were impressed with the build quality. Per the company, each light features 25W/30W/35W/40W/50W adjustable wattage and 3000K-5000K switchable CCT via side stack switches.They have smooth 0-10V dimming from 10% to 100% for good brightness level control that is flicker-free.Using the instructions, my husband and his brother installed the two lights into a T-bar drop ceiling without too much difficulty.Afterwards, the garage looked great. We loved the bright LED light that illuminated the whole garage. It could be dimmed easily. There was no flickering.We definitely recommend this two-pack for those who want modern, sophisticated non-fluorescent ceiling lights.

If you are updating old, flickering fluorescent tubes in a shop, office, or basement grid, these 2x4 LED troffer panels are a massive upgrade. Instead of being locked into a single brightness level or color tone, the built-in switches let you customize the output perfectly to fit your workspace requirements.Product BreakdownMulti-Wattage & Color (CCT) Selectable: The versatility here is exceptional. With 5 selectable wattage settings (25W up to 50W) and 4 color temperatures (ranging from a warm 3000K to a crisp 5000K daylight), you can dial in the exact atmosphere you need. It completely eliminates the guesswork of buying the wrong style fixture.7500LM Brightness & Diffusion: At its peak setting, the 7500-lumen output is incredibly powerful and easily fills a large room. The lens diffuser does a fantastic job of spreading the light uniformly, completely eliminating harsh glare or distracting hot spots across your workbench or desk.0-10V Dimmable Control: The fixtures support standard commercial-grade 0-10V dimming. When paired with a compatible dimmer switch, they transition smoothly from low-profile ambient lighting to full-blast task lighting without any buzzing, humming, or flickering.Fitment & Commercial StandardsStandard Drop-Ceiling Fit: The ultra-slim, lightweight housing drops cleanly into standard 2x4 T-grid ceiling layouts.

This easy to install LED Troffer 2x4 light fixture by LANGGAN is a really nice, commercial quality fixture producing 7500 lumens for only 50 watts. In addition, the power consumption can be reduced all the way down to 25 watts, and is dimmable. It is great that you can change the color temperature in 4 settings from 3000K to 5000K. All light fixtures should offer that feature because everyone's tastes are different. I personally prefer 5000K or even higher for my lighting scenarios, but it is easily adjusted to a warmer color by simply changing a switch. This fixture is very slim and lightweight and is easy to handle and place into position in your ceiling grid. The price is very reasonable considering all of these features and is a good value, especially for two fixtures. Highly recommended!Review for: LANGGAN 2x4 LED Troffer Light, 4CCT 3000K-5000K, 50W /40W /35W /30W /25W Selectable, 7500LM, 0-10V Dimmable Commercial Ceiling Light, ETL&DLC Listed, Drop Ceiling Light for Office School Hospital 2 Pack 2607-023
