ideas for a sun circle
 

I'm in the process of setting up a hydroponic system, I am going with a 400hps & 400mh I am in now in search of ideas for a sun circle. I have found them but not cheap, HELP.

Here is my first mover I built 15 years ago and it still works. Made from a barbeque rotisserie motor and a 90 degree gear reducer that weighs about 30 pounds. The light is connected to a ball barring made from a bicycle axel. The light cord is connected to a wall causing the light to rotate as the mover goes around and around. This set up will only work with one light because with two the cords would get tangled.
