Hi, we are still in the process of finalizing our pool build contract and have a question about lights I hope you all can help me with...like the title...how many LED lights do you all recommend for 16x32 rectangle pool? One pool dealer we delt with suggested two (I can't remember if they were LED or not). The pool dealer we are going with said only one light is need, specifically stating because it's a LED light. Please help, what are you thought?
