I went away for a week and came home to find the quick change plastic lens cover sitting at the bottom of the pool. It was cracked down the middle (it was rather old and my guess is the pool cleaner had something to do with finishing it off).
Anyway, I went to turn on the underwater light and it was out. It looks like the fixture is about 1/4 filled with water. I've had the pool a little over a year and never had a problem with the light.
I want to change the bulb. Is there supposed to be water behind the glass lens? If not, and the water is what caused the bulb to blow out, what do you suppose caused water to leak in? As I said, it worked great since I've owned the pool. Will it work if I just set the fixture on the deck and let it dry out, or do I need a whole new unit?
