Hi all this is my first post! I just found this sight and now know how to SLAM my pool this spring. Anyway one thing we don't like about our pool is that is does not have a light. Is there any way to add an effective light to the deep end? There is not a niche. It is a 20x40 liner pool probably built in the 70's. Good shape but no light. Not real excited about a floating light either. How would I do this? Thanks!
