We have drained our pool for some cleaning, and I was planning on replacing the light, it’s a 120v older starite with the LED color bulb, it’s not quite bright enough for our pool. Florida Sunseeker now makes a 35w lew nichless fixture that will retro fit but I need to wire in a 12v transformer, my question is can the small transformer they sell be wired in the Junction box that sits above the light, or does it need to be wired in by the switch? Thanks.
