We purchased the black version.  While expensive, it's a beautiful piece of art. Our GC mentioned that he would want to put that up in his home (always a compliment). And it's not overly heavy, so structural reinforcement isn't necessary.  The color is about 3500K (not yellow-ish but not exactly bright daylight).

Pros
* beautiful work of art
* bright enough to shine as a foyer light. Also dimmable, but I haven't tested this yet
* large/tall with enough wiring to hang form the ceiling (10')
* quick adjustments make it easy to adjust the light

Cons
* the base does protrude about 3-4 inches from the ceiling and really should be situated such that it is inset and flush with the ceiling. This is not a problem for really high ceilings where the base is hidden. You could also paint it the ceiling color, but we haven't chosen to do that.
* could be a bit whiter (4000K)
