I need help finding a Pentair Amerlite spa light (4") in 120v with a 100 foot cord. The pool repair guy says it has been discontinued and to convert my spa light to LED was quoted at over $1700. Also it won't match the incandescent in the main pool if I change it out. We use the light maybe 5 hours a year. Currently, when you turn the light on it trips the gfci. The same pool repair guy replaced both main pool and spa light bulbs 2 months ago. It was tripping the gfci then too. Any idea where I might find one? He said his suppliers don't carry it any more and said if I can get one he'd install it. Thanks.
