This is a cool lamp. It’s really great in a new remodel master. I was able to get it to stay in place and it only moves vertically as I expected.  However, it is definitely antique brass as it states but the picture shown is not a good representation. If you are looking for antique brass it’s awesome.  I placed the black  the brass side by side In my master bathroom trying to figure out which to go with.  Picture probably doesn’t do justice. I will try again.
