They are actually great enclosures...a little pricey but very nice. They actually make them about 20 mins. from where I live. I think I know what you are asking because some of their enclosures are very tall and meant for lizards like iguanas. As long as the your beardie could get to within the recommended distance from the UV light I would think they would be okay. They do make enclosures that aren't so tall that would probably work much better...I think one of them is something like 5 or 6 ft. long 2 ft deep and about 2 feet tall. I was looking into them awhile ago also. Hope this kind of answers what you were asking.
