RGB LED light system to replace fiber

Mar 3, 2013
I have a 50' long vinyl pool that currently has two fiberoptic lights on each end. There are two Fiberworks MR16 photon towers that power them. I want to change out the 4 lights with LED. Wondering what the brightest option out there are that will fit and what sort of control system i'll need for them. I'd like all 4 lights to be on the same color change cycle.
