I purchased the white ones and since I have an open canopy I made my own bar for it. The light picture didn't come out as nice i will post another one later.
Those are good ideas as well. This bar can fall in it is possible but takes a real push to knock it. I should have made it longer and cut the 90degree elbow a bit for support. I was going to hang them as well. Shelf is a good idea. I'm going to work on making it so it won't fall in.
