I want to change my white spa light to a color changing LED. I cannot make out what type of spa light I have. I am assuming it is a Pentair as that was what my pool was and it is a pool/spa combination. The bulb I removed is a Phillips 100W 120-130V. Do you have a recommendation? The measurement is 3 inches long by 2 1/2 inches wide. But a 3x3 would fit.
