need light mounting ideas

[GratefulReef]

I am purchasing an ati 6x54w t5 fixture the powermodule, I am unable to hang it from my ceiling. What other ways could I mount this fixture, I'm thinking that right on the rim would put way too much light into the tank. My tank is a 75g standard mixed reef with some sps and I would like to add more, I also have a bta and a squamosa clam. I need something that wont require me to modify the walls, ceiling or floor of my apartment in anyway. Thanks in advance.

Here is one way using electrical conduit.

I used this idea to make 2 supports with a single 90 degree bend.
I used conduit strap clamps to attach them on the back of my stand.
This held up a T5 6x24watt fixture.
