We ordered two of these lights for our foyer and stairway.  Other than the instructions being a little vague, the first  light installed no problem.  However, on the second light, the bracket that the light screws into was milled wrong so that when one mounting screw would go in, the other would be way off.  We took everything down and discovered that the only way the second screw could go in was at an angle.  We McGyvered a solution, but it would have been nice if all the pieces were made the right way.
