Question: Does the 19" dimension refer to the outside diameter?  The circular mounting frame in my fixture measures 17" diameter.  Is this the correct product?
Document: We were replacing a square unit that is no longer in production and wish this was our original fixture. It was simple to install, sharp looking, and very durable. It is an elegant addition to our kitchen.
Very disappointing. I have one box &#8230; with broken glass, but not enough to have been bulbs, and no acrylic cover. So, if you go by my experience - there's no cover and no bulbs. We're going to have to buy something else. It's a shame, because it would have been the right size.
Answer: no
