I have a 1977 inground plaster pool. There are two submerged 120V lights; one in the pool, and one in the spa. When I moved in only one of them worked. I pulled both cans out, replaced the bullbs, and reinstalled the cans. There is still a ground fault somewhere in the circuit. I had an electrician come out and spent 4 hours trying to fix it, calling his boss 4x for advice. He gave up and hasn't come back. I called another electrician and he said it sounds like I would have to run new electric supply to both junction boxes. This would involve more ugly surface mount conduit runs, and no guarantee that the other buried part of the run is sound. The damaged section of conduit is buried under concrete; I'm not digging it up.
At this point I could have the new electrician install the two new supply runs and hope that fixes the problem ( and that the run between the junction box and niche does not rust through eventually)
Or investigate other options - I know there are a lot of new products out there, but I'm kind of overwhelmed by the options. I see some powered by the return jets - or a battery-powered LED that you just toss in the pool. These all seem flimsy and prone to failure. Is there a solar-powered option to bring power to the junction box without a conduit run?
I just want to be able to swim at night, I don't care about a dancing disco ball with all sorts of colors. Just two white lights that I can turn on manually when we want to swim at night.
