Yak Yak Yak,
This is so simple,
I just suspended my 48" T5's with 2 eyebolts and HD line, lightweight unit. BUT depending on your weight of hood/fixture, just add pullys.
Each pully per anchor, distributes 1/4 to 1/2 the weight, each loop takes another percent. 100lb hood, 2 2-spool pullys, lift weight 25lbs, 3-spool, like 10lbs pull. I just put drywall screw into wall and lift, hook, done. light stays horiz and you see what your doing.
Something like that, just made it up anyway.
Ex Navy, I remember something like this but at my age....
