This occurred 2-3 times last year, and once this year. Pool light is a standard type (Halogen I believe), located a few feet down under the diving board. Light operates fine, turns on and off. But on very warm days, when the pool water is very warm, the light will suddenly turn off. If I don't do anything, it often comes back on in about 15 minutes. I normally will turn it "off" and wait 15-20 minutes, and if I turn it on, it will come on.
It seems like it's getting hot and turns off when it cools sufficiently. This can't be normal, right? Do these fixtures have some sort of thermal protection that does this? I'm mostly nervous that there is a problem somewhere and I don't want someone getting electrocuted. Should I replace the entire fixture and be done with it? If so, I guess the fixture and cord are one piece and I'll be snaking it back to the JB?
