LEDs have come a long way the past few years. This light is phenomenally bright. More than I expected. I installed it my shop (see photos) and it's the brightest my shop has ever been. Apparently you can add a dimmer. I may do that someday. I may also relocate it to my shed where I could use this level of brightness.
Installation was a breeze. There's no power cord on this baby. You have to hardwire it. But it's pretty straight forward: black, white, and green. The support cables are kind of goofy. You can adjust it higher simply by pulling the cable from the bottom of the barrel that secures the cables connected to the fixture. But you can't go the other way. If you pull it too far, you have to take apart the barrel which has small balls and springs that can be difficult to reassemble properly. You also will need to supply your own hooks for the ceiling.
I think if I were to get another one, I'd go with the 130w version. It's half the price and half the brightness - no dimmer needed. Nonetheless, I'm still happy with this one but I sense I will be getting a dimmer switch for it at some point unless I relocate to the garage or shed.
My one complaint is with the instructions which do a poor job of explaining how to wire the dimmer. And there is zero information on the auto-on motion detector feature which I don't need but have not figured out. It's not even clear to me if I have to buy something extra or if it's included and I don't know how to enable it.
Overall, this is a super bright light and I'm happy with the quality. It uses less power than incandescent lights of equal brightness and LEDs last for 20 years or more.
