Great advice! I’ll definitely open it up and see what I can do.Then you are good to go on finding a color changing light fixture. I pulled out the old ballast and fluorescent ends, cut the wires as close to the transformer as I could which is how I wired in the new light fixture. Remove the hex screws on the top and remove the top metal lid - you'll see exactly whats going on inside the top area. Leave the distribution block alone as that controls the downlight wiring.
