Here's my setup for raising lights off the top of the cage:

The pvc frame is pretty simple to make as long as you have a drill and pvc cutters. The frame is about the same size as the cage. You want the weight of the frame to sit on the aluminum frame and not the screen--though isn't necessary for holding single bulbs. The quad fixture I'm using is pretty heavy, so I made sure it sits on the frame.
I put hooks along the top so I can hang lights.

I've never used the frame to hang a single linear uvb fixture before though. You could get 4 cables and drill four holes into the fixture to hook them onto (see drawing below). But otherwise it might be difficult. If you go this route, you would need to remove the bulb from the fixture. Then you would need to drill the holes in the corners without bending the fixture. You would need to hold your fingers on the inside to keep the drill bit from pushing into the frame. If you aren't comfortable with threading the drill bit in between your fingers on the otherside, I wouldn't recommend this method. It will work, but it requires a decent amount of DIY which can be annoying to some, including myself at times.
