Pool Light Leak

Postby palmeroj » Sat 22 Jun, 2019 19:25

The incandescent light filled half way with water. At first I suspected the lens gasket, but after taking it out I noticed a drip coming off the end of the cord where it enters the metal case.

Is there a way to fix this with some epoxy or do I need an entire new light?

Any suggestions greatly appreciated.

New light and buy LED, 85% cheaper to run and far more reliable.
Old incandescent pool lights get hot when on and then cold when off which expands and contracts cable fixings etc so they fail, LED do not seem to suffer this issue as they don't get as hot

Well... yes. That's the best solution; a new light. But it will require running the cable and emptying the pool at least partially. Although, I've seen you tube videos where this was done underwater (the guy had scuba gear).

I was wondering if anyone can recommend some type of silicone or epoxy sealer to resolve the issue at least temporarily.

Sealing it and putting it back would be much quicker since I can reach the light from the deck without having to lower the water level.

Much appreciated.

It shouldn't, the cable runs through a gland fitting and should be long enough to reach the pool deck allowing the change to take place at the surface. The cable should be wound around to take up the excess, that's why light niches are so large.
If you want to try and bodge it, something like Sika flex EBT might do it.

Thanks for the suggestion. I was thinking that area probably gets hot. I started looking for a product that would resist high temperatures and came across 732 RTV Sealant from Dow Corning. Temperature ranges from -76 to 350 F.

Sealant seems to be working, but I’ll give it a few weeks to know a for sure.

Eventually I will follow your suggestion and replace it with LED.

Any recommendations for a good LED light?

Thank you.
