Go to the big box hardware strores. I use small chains on my Floresents and yes adjsuting them takes a few minutes but I'm not too worried about them falling on my plants. I use metal hook attached to a ceiling stud to attache them. Lowes , Home Depot, and Walmart have everything you need.
I have yo yo's on my HPS reflector but I put safety chains on them to falling on the buds in case one of the little yo yo strings breakes.
