I have 2 Jandy CPHVLEDS50 lights in my inground pool operated by aqualink 2.0 controller.   I also have a separate spa light with same automation, but operated separately. 

 

After GFCI continually tripping, I was able to diagnose which of the 2 pool lights was bad.  Unfortunately, finding a new Jandy watercolors light is difficult and quite costly.  I am wondering if it would be advised to just switch out both pool lights with a compatible niche-fit light, but concerned the automation may not work.

Secondly, an option is to use another light instead of Jandy, but will it even function with the aqualink 2.0 unit.

Not an expert, looking for some advice.
