I am just getting ready to install a 16X40X24 Grecian L shape vinyl pool. I was thinking of only putting 1 Colorlogic light on the outside edge, near the center of the pool. I was thinking this would cover the entire pool, not leaving any shadow spots. My builder wants to charge me 1000 for an aditional light. Is one light enough, or should I press for 2 and make him give me a more reasonable price?
