Thanks for the video and am trying to do a similar thing to tuen my home office into a studio. I am new to the world of light rigging too. I think plumbing supply shops sell short pieces of pipe (like 6"to 8" that are threaded on each end you can use for the flange in the ceiling to your main pipe. And they have the amusing name "galvanized steel nipples." I am not making this up. lol
