hey guy so here is my problem(after much looking i can't find a vertical Light mover). i have 4 lights that need to go up and down automaticly, just like a light mover that would go from side to side( just up and down instead). so im thinking that a eletric pulley for lights would work fine, but i need some sensor to lower them to a point and bring them back up to were they started. any idea's of what this looks like........
