I purchased an inground pool with a spill over spa last year. The pool company received a spa with a light in it although it was not what we ordered, I guess they decided to keep it and make it work for us. We had it working for about a month and then it went on the fritz and stopped working. I have to admit the light with the red cover looks beautiful at night when the pool is lit up and my wife loves it. Now that we have seen it working we want it to work all the time. My pool guys came over last week and opened the light in the spa and found water had got in so he replaced the gasket and ther plastic housing and put it back together and our light works once again. Second night I went out and turned the light on and zippo...not working again. in my frustration I went over to the spa and banged on the top stair over the light and it went on. Hmmm loose connection? I called my pool guy to get him over to look at it and he told me that the old cover that they took out the week before was melted from the heat of the bulb and thats how the water got in. He also said but was not really sure that the light is supposed to turn off after 15 to 20 minutes of operation and then return itself on again, which sounded weird, but maybe thats how they work although ours never did that. I am waiting for him to get me the number of the mfg so I can call and figure out just why the bulb would get so hot as to melt the lense allowing water to penetrate. The light is a low voltage and runs off a transformer that simply has a push button to turn on and off. The problem with that is you never know if the bulb is blown...is it on or off. Strange controller switch if you ask me. Anybody here have a light in there spa and does it turn on and off automatically to keep the heat down? I need the truth!!!
