I am looking to replace both my SPA (burned out) and Pool lights (stuck on one color). I need some assistance on the replacement bulb that I need. My pool and spa was built in 2005. The paperwork I have indicates a Pentair SAM lights SPA (100W) and Pool (500W). I would like to switch them to LED if possible with minor changes. Otherwise, I am okay with just replacing the bulbs with the same exact ones. But I am not sure what bulb will work with my system. 12V or 120V. What kind of connection do I need? Is it similar to a flood light or does it have a 2-prong socket. My goal is to have the correct part before I start the project.
