OK, I've been working on this the last couple of weeks and this is what I've come up with. Quite a few changes since the first big ugly pipe thingy.

This one clamps to the tank, has a cutout for tank frames, and will swivel where the clamp and arm join so you can put the light where you want, and out of the way when you need to.

I'm pretty happy with it so far, but have a couple more issues to overcome to be satisfied.

Forgive the poor pics. :|
