This is an attractive fixture but the light diffuser does not fit. The nipple is too long and the diffuser is well below the shade. Of course, since it is the last step, I have to try to find another nipple that is shorter so the diffuser will be flush with the shade. The fixture is already up so I hope I can find a solution. The manufacturer may want ot check this. Some kind of clip would be nice to hold it in place.
