Here's an update. I took the handle off the ballast, and the nuts holding it on fell into the case. I opened up the case and took them out. No problem. I heard back from the company, and they said it would work just that way. They also said that putting it on its side would be no problem.
As far as the lighting goes, it is beautiful!! I think though that I want a second fixture. The ends are noticeably darker. I haven't yet put the VHOs back in, so that might take care of that well enough. My lamp timer works just fine. I did mount the fixture too far back, and I will make that adjustment. No big deal.
Thanks so much for the help JJ and everyone else who weighed in. Seems like a great choice.
