Hayward Underwater Light

[cwoav8r]

I have a Hayward SP-570 underwater light and the color changing LED bulb I bought from Amazon just failed (over half of the blue LEDs). I bought a new LED bulb from Florida Sunseekers and the lens gasket they sent did not fit, so I reused the old one and of course it leaked. I went to my local pool supplier and the only gasket they had was an SPX0580Z2 which was substantially thicker than the original SPX0540Z2 (very similar to the one I got from Florida Sunseekers) and the band clamp is no where near wide enough with my SP-570 trim ring. I went back and they found me a clamp for the 580 and it was indeed a little wider than the original so I assumed they made it wider to accommodate the thicker gasket, but no, still not close.

So I have three options:
A - go to another supplier tomorrow and find an original SPX0540Z2 gasket
B - take my 570 trim ring and compare it to a 580 trim ring to see if the mating surface is thinner to accommodate the clamp
3 - replace the light housing with something compatible with my niche so I don't have to try to find parts for a 40 year old part

If anyone has had a similar experience I would love to hear from you!

Oh, almost forgot "fresh water only"... does that mean "bad" as I just switched to salt???

Thanks!
Ed

Unless a different type of sanitizer is used, all pools that have ever had a chlorine compound put in them are "salt" pools. That is still a fresh-water pool. Some SWG can operate at levels of 6000ppm, but most a little over half that (less than the average salinity of human tears).
True "saltwater" is in the range of 35,000ppm (sea water). It did not damage your light.

So, the fix was A. I found an SPX0540Z2 gasket and an SP-580 trim ring... the mating surface of the 580 trim ring is indeed half the thickness of the 570, however when I dry fit it to the housing, holes just didn't line up. I am sure I could have "made" it work, but I already had a brand new 570 trim ring to use. So far no leaks.... looking at the original gasket that leaked, I'm pretty sure I pinched it when I tried to reuse it... and I didn't lube it either. Lessons learned

Kinda what I thought, just wanted to make sure. I had heard that for pumps etc. there was a different set of o-rings for SWG pools. Just making sure.

Thank you!
