I have Alumnaire II lights in my inground pool.They are 120 volt lights. I want to replace them with LED lights. I found lights on Ebay from New Zealand that are nicheless and are a good fit. The lights only came with about six feet of electrical cord. My electrical breaker box is 40 feet away. The lights are 12 volt AC. I will be using a 120 to 12 volt transformer in the breaker box to power them. Is it safe to splice the wire realizing that the splice may be in water? I will be using a certified electrician to do this. He assures me that he can make a water proof splice and since it is low voltage there is no risk even if his splice were to fail sometime in the future. Does this sound safe and reasonable?
