We have had our pool for 3y 5m. Probably used our SAm 100 hrs max. A couple months ago we noticed we were losing colors. We are now down to red, green and yellow. According to a website this is a 7 color light. We are past warranty. Called Pentair who did not have a clue other then to say that someone needs to come out and take a look at it. I am a little ticked since brochure claims this light lasts up to 4,000 hrs. Any ideas? Anyone have this happen to them? Anyone do this themselves or do we have to call professionals? Thanks so much!
