I have been gone afew months as of late but i am back and i have a few new tricks. Most of us have probably seen the adjustable light hangers
http://www.shop.maxxpower.us/images/710115.jpg LIGHT HANGER, YO-YO, GROW YO YO, LIGHT MOVER, LIGHT RAIL, LIGHT TURNER Well they say right in the description that it "WORKS LIKE A MINI BLIND." Well what do you know a mini blind work like a mini blind too, and @ 1/6 the cost of the commercial light hanger.
Start by tearing the blinds themselves out along with the bottom piece then cut away all the small strings that held the blinds leaving the biggest cord on each side intact. You should be left with the top piece, a single cord on each end aswell as the 2 pull cords used to adjust the height of the blind/light. Now just attach the main piece to the ceiling and tie each of the 2 blind cords to your reflector and you have a light hanger that is so easy to adjust it is perfect for those w/ limited mobility aswell as those of us who are just lazy or tired of playing w/ chains. I have tried to be as clear as possible but if there are any question please let me know and I would be happy to help.
Also the torn out blinds can be trimmed down to make great plant label stakes instead of throwing them away.
***Edit*** I use these to hang floros and even large air cooled HID reflectors w/ glass lenses and have good results but i would not use them for a light with a built in ballast as i don't really knoiw how much weight they can support and that would seem a bit much.
