Update! Lights are mounted!! I used 10 series t-slot for the light rails. I'll make another thread to show the materials and explain the whole system, but here are some of the pictures from when we were testing the mounting in the garage (we figured that was safer than testing the mounting system over the tank

).
And here it is mounted over the tank (ignore the cables...cable management is something that's still on the "to do" list).
I made a tutorial thread for anyone who might need to try to figure out a way to mount Orpheks in a canopy moving forward.
HERE IT IS.
