So I have legacy pool. So far, I have replaced the pump, controller and much of the piping. Now the wife is on me about the pool light not working. The power is there and it doesn't surprise me that the light doesn't work. Before I start messing with it. Are there pool lights that require draining the pool. Sounds absurd, but if it was cheaper, this guy went that way. Also, any horror stories of holes forming around light fixtures such that when I start messing with this, it somehow sets off something more concerning? I imagine the light fixture is 10 years old, give or take. How long do pool liners last? I know its not a LED light (given the age). Are there issues with me taking the bulb out and not replacing immediately, as I will need to source a replacement, once I determine what sort of bulb it is.
