Anyone have recommendations to a adjustable hanging fixture for lights. I have a 6 bulb T5 unit that I currently rest on the aquarium. Due to it's size I can't use legs. Problem with this is it limits me from access to the tank. I would like to utilize some sort of adjustable hanging system to raise and lower it when needed so I don't have to remove this heavy and awkward light everytime I need to get in the tank.
