Hello all,

I am new here to the forums,but I was hoping one of you could point me in the right direction.
I have a Hayward sp-563-l pool light that has lost its waterproofing , and the internals are rusted out.

I can't seem to find a exact match for a replacement, I was wondering if I use something different if it will fit in the old niche(screws line up, not to big/small). Thoughts anyone.
