The fixture is listed as being LED compatible and dimmable as long as it's installed with a dimmer switch.  I've installed two out of three so far and they both have a buzzing noise when you turn them on.  One is installed on a dimmer switch and the other is just on your regular standard switch.  The one on the dimmer is installed in our bedroom and that buzzing sound is so annoying that there's no way we can live with that.  I'm not sure if the fixtures are defective or if they're not really LED compatible.  Like I said, it doesn't seem to matter whether they're installed on a dimmer or not.  Love the look of them, but I'm apprehensive to install the third fixture.
