I'm wanting a light for my pool and as already stated in another thread here I may need some new gaskets in my return anyway. I'm not even sure I want a return light combo but some of the hang on ones I've seen on Amazon have gotten horrible reviews. I don't have to do Amazon but I've got " Prime" so I look there a lot first. One of the return light combos I saw was a Pentair and it looked good but something was said by a reviewer about it not being for use in a saltwater pool. I also couldn't see exactly what kind of return piping it accepted. I just hard piped everything to get away from hoses and used a 1and 1/2 inch MPT fitting to go into my present return. I mean what all are my options? Is the saltwater thing really an issue? Are the "hang over side" light all junk? Help needed from the experts please!
