ASD 2x4 LED Flat Panel Light 40W (100W Repl) 4000K (Bright White) Dimmable 2x4 Drop Ceiling Indoor Commercial Fixture 4643 LM 120-277V, UL, DLC 2Pack

Great product overall. Very easy to install into my existing drop ceiling in my basement family room. It took longer to get the old flourescents out than to put the new ones in. They are brighter than I expected so I will definitely be adding a dimmer eventually. The only downside is that they are not set up for multiple units to be wired together but that is easy enough to work around.

I bought these for a finished basement room with a drop ceiling. It had four fluorescent fixtures that had become troublesome because the ballasts were dying. They were the older-style ballasts that are hard to find these days, and I considered replacing them with newer electronic ballasts. But this would require rewiring the fixtures and new ballasts—two per fixture—wasn't cheap, so I decided to upgrade them to LED.I'm glad I did. These new fixtures were very easy to install and give off more light than the original fluorescents. The whole job took under an hour and the biggest problem is recycling the older fixtures which are made of heavy steel sheet metal.

The lights are great and bright, glad I did not order the 5000K, as the 4000K are plenty bright. Had a problem with my first order as a lens on one light was broken so I had to get a replacement. Easy to install, but the packaging leaves a lot of probability for damage. Second shipment was fine.

From a practical standpoint, this is equally as bright as a 2x4 troffer with 4 florescent t5 bulbs. Theres no way to mount it in place of the troffer easily. The surface mount kit is in the $30 to $35 range.It's fine. I can find no fault with it, but it is also not a troffer replacement. The lighting quality offers no noticeable difference over traditional florescent offering. The power savings will take some time to offset the cost.Personally I'm disappointed as I really wanted to buy into LEDs for my garage, but this isn't it.

We are in the process for replacing our flourescent fixtures with LED fixtures. The ASD fixtures are very bright and give the suites that we have put them in a more inviting feel. I am very please with my purchase

I used these light panels to replace the typical, white, industrial-looking florescent light fixtures that my finished basement previously had and I couldn't be happier. These cast much better light, look much better style wise, and now I don't have to deal with the annoyance of replacing and disposing of long florescent bulbs. These panels were trivial to install given that the wiring for the previous lights was already in place and the panels fit perfectly in the existing framing for my drop ceiling. Highly recommended!

This was not very bright. Install was ok thought it would be nice if it included a connector and wire nuts.

These are very nice. I’ve installed about 20 of them now and no problems. Just a few minor complaints:1. They don’t dim to a very low level. Would be nice if they could dim a little more.2. Minimal documentation3. I received 3 boxes of 5000k when I ordered 4000k
