This is an *absolutely stunning* fixture with two major flaws.
First is that the installation bracket is such that it is not possible to install the light in an arbitrary orientation. The net effect of that is that it may not be aligned properly to face the direction you'd like to face the bars. You'll have to rig something up yourself to correct this or change the orientation of the underlying electrical box.
The second flaw is that there is no top cover for the drum shade. So if you install this in a location where it is possible to see down into the fixture -- for example, close to stairs -- you will be able to see the internals of the fixture, which really ruins the beauty of this.
There is a minor challenge with the installation as the electrical wires that it ships with are designed for pendant and flush mount installation so you will have to separate the line and neutral wires manually (with some difficulty).
Otherwise, the installation is not too hard.
