My pool lights are the 8" Pentair type. The bulbs (500W) had gone out in both, so I recently replaced the bulbs when I was draining the pool partially. When the bulbs had fused, they did not just go off immediately as I have seen other incandescent bulbs do... the brightness sort of faded over a few days and then the light would not come on. When I replaced the bulbs, I also replaced the white gasket that goes around the lens.
One of the lights has a little water smile in the bottom of it, which i can see from the pool side. i think I had seen this before, prior to replacing the bulb. I'm worried that this could cause a problem if the light is on for a while. Any suggestions as to how I can remedy this? Sounds like a leak, but I would like to not replace the entire light unit if possible.
