Another Light Question

[kelemvor]

I don't have an answer, but I've got the same issue with the staining below the light. I'm curious if there's a way to clean it up myself.

Consider this a bump.

I have the same problem. We resurfaced the pool in June and the first rust stains did not appear until 3 weeks later. New plaster - now with rust stains. The light was, of course, pulled for the resurfacing. I replaced the light seal after pool was filled, when the GFIC kept tripping and we saw water behind the glass.

We didn't replace the light. I'm beginning to wonder if the heavy acid demand of a new pool might be causing the back of the face plate or other components to rust. I'll pull the light soon to explore, but dread it. In the meantime, anyone know how to get rid of nasty rust stains around light niches? Or what might be causing the issue?

Hey all.

The niche is permanently embedded in the wall of a 'crete pool, which means you, not only have to bust out part of the wall and repair it to change the niche, but you'll also need to reconnect the conduit. Both these things would 'probably' include having to cut out a section of the deck above the light.

If it's just the light itself, you may be able to seal the metal so it won't rust further and treat the stains with ascorbic acid.

Please let us know.
