I looked at the Carlisle picture you mentioned and I actually have 2 of the light fixtures like the green one in the picture but that top also has a 1/2 inch threaded hole in each side, in order to screw in more light assemblies! Mine happens to have the black plugs screwed into those holes, and like I said, you don't hardly notice them. Mine also have the cute little rounded finial on top and it does sort of clean it up a little! That type of top is a little smaller than yours and not quite so obvious, but if you just get a few plugs for the holes and put the thing together and get it up in the air----you might like it just fine! I really like that rounded top but you don't really notice the top piece anyway, when the light is in place and displayed! Try it!!! You'll like it!!!
