Since pool was installed, about 1 1/2 years ago, I've had to replace all three SAVI LED lights. Just the other day, one of the replacements went out. I only have the lights on about 4 hours a night. Spa version of light has never had problem. Was wondering if anyone has had issues or problems with these lights. I think PB is getting tired of replacing (they have a 2yr warranty) but very concerned once that runs out. When they work, they are very nice and I would consider them a perfect light. However, if they only have a few months life at 4 hours/night then something just doesn't seem right.
