Light hanging help

Already posted in my build thread but I think more people will see this here...

Going to be hard to explain but looking for light hanging help.

I need to hang my two reflectors. I was thinking to build a rectangle out of aluminum to bolt them both to and then hang it. So very basic. What I am wondering about though, is how to hang the whole unit. I was hoping to hang it how pool table light racks are often hung...(heres where I can't really explain things) so that there are four cables bolted in each corner that then meet a few feet up and in the middle...make sense? So that only one cable is bolted to the ceiling.

But this seems like it would move around maybe? Will it stay steady? A heavy fixture would have an easier time staying steady but this would be so light. Am I better doing this a different way?

Or any other ideas for hanging the lights? Even thought of doing something like rods from the back of the stand that extend out over the tank and the reflectors hang off of them but I think this would be ugly.

Looking for ideas because my ceilings are 14' high and concrete. I don't really want to be drilling them too much. I also think its going to look silly having the lights hang down so far...
