I've had my pool for 4 years now, using TFP for 3 of them, and I love my pool! I have never cleaned inside my light niche because I'm chicken to take out an electric light in water!!!!! And I work for an electric company. So, if I turn off the 2 breakers in my pool breaker box where my light switch is, and get in the water to take the screw out and take the light out (it's too low in the pool to do it from the side, and anyways whether I'm fully in the pool or only partially when I get electrocuted it won't matter), then you SWEAR to me I won't get electrocuted????? Is there water in the niche, so that if there was a short or an exposed wire, it would have already shorted out so that's how I know the unit is intact? The light works fine now, I just want to see what's behind it, if it doesn't kill me.
