Can you ask them, if they can give you a ballast in arm fixture?
I emailed them last summer, with pictures of the two models and said I was interested in any they replace. They replied to call them, so I thought I was getting somewhere. But when they called me back, they just said that they scrap them out. I didn't push the issue, but they didn't seem too interested in letting me have one. They just said if they replace them, they aren't any good. But most likely, they probably just need a new bulb I would think.
