Pulley System

[mike31154]

Ok, I found some info on the units similar to the ones I've been using since hanging my my LED fixture. They are retractable reels & are often sold for hanging planters to raise & lower the flower pot for watering. You do need to ensure they are sufficiently robust to support the weight or your light(s). I believe the ones I have can hold up to 30 lbs. I use 2, so potentially can hang a 60 lb fixture on them. It's always a good idea to leave some room for error, i.e., don't max them out. I'm sure with a bit of searching, one could find more heavy duty versions, capable of holding more weight. A quick tug releases the reel mechanism & you can raise or lower what's attached quite easily & lock in position at the desired height. The carabiner fittings make it simple to unhook your cable/rope/chain or whatever you're using as attachment hardware. Mine are starting to get a bit finicky in reel operation these days, but for the price, they are easy to replace. If you want to keep it simple, without motors & wiring, this is an alternative solution.
