My Pentair SAL color light in my spa was not working so I drain the spa and pulled the fixture out. I have moisture in the fixture and the gasket was definitely deteriorating so i know the gasket needs replacing. I am hoping just the bulbs need replacing. There are 3 - MR11 FTF (650037) and 1-MR8 (650036) bulbs to replace. Does anyone know what is so special about these bulbs where Pentair wants $20+ a piece for MR11 and $40+ for the MR8. This seems a bit ridiculous considering all the bulbs on the market. My question is does anyone have any recommendations for bulbs or have you used any in lieu of the ones sold by Pentair? I have found MR11 bulbs from $2.50 to $10 that would seem to do the job. MR8 bulbs are little harder to come by but I have found some for $5. I guess if I go by the typical pool manufacturer markup then these prices seem logical, but I just want to make sure I am not missing something. I also thought about just replacing this with one of the cheaper LED color options out there. I have to do research to find what if anything will fit in my fixture. Any recommendations?
Also, specs are almost impossible to come by for these bulbs. Does anyone know, exact dimensions, lumens, color temp, and beam angle. I doubt it will make as a big of a difference in my spa, but why not try to match the lights as closely as I can. or has anyone replaced these with MR11 and MR8 LEDs?
Any information would be greatly appreciated. Thanks for your help.
