I have not installed the lights yet, so I can't comment on the installation process or overall quality.  When I first opened the box, I was surprised at how bright white the shade is.  The color I purchased is called Ivory, which would certainly seem like an off-white.  Maybe when they are hung and the lights are turned on they will look more ivory.  We will see!  The fixtures are beautiful.  I am generally not one to complain about anything and am not complaining about the lights, just warning fellow purchasers to expect bright white if you order the ivory.

Beautiful
The color called Ivory is actually Bright White
