I used T track like used in woodworking to make fixtures and jigs.

By mounting a couple pieces front to back, it gave me freedom of movement both front to back and side to side so I am able to adjust the two fixtures for best coverage. I can provide more info on nuts and bolts etc. if you are interested and I think I did a write up at the time on a couple of the forums.
Here is one:

I considered hanging mine and eliminating the canopy but I hate all the light in the room. It looks like an arc welder is going and makes it hard to watch televison or do other things. The LED is not as bad as the MH and VHO was but it still lights a room up.

I have seen people make a bracket using electrical conduit sweeps and connectors that looked pretty nice though when mounted to the back of the stand. Others I have seen used aircraft cable and hooks in the ceiling to accomplish the same thing.
