Love this now that it is up.  Huge amount of light, so use a dimmer if it's not a super high ceiling. I do not like the ceiling assembly unit which is non-standard.  Most lights attach directly to the support bar and then canopy gets attached.  This light attaches to the canopy and then you have to prey you can find the down-screws and get them through the canopy holes.   No way to do this alone, even as an experienced builder.  Took 2 hours to attach working over my head on a ladder to do something that would normally take me 10-15 min.
