radion gen 3

I have a Planet Aquarium tank that is 36"L x 18" W x 24.5" H Was wondering what lights should i run on this tank for maximum coral growth/coloration. I have a Gen3 Radion xr15 on it i believe right now. (came with the tank) I want to change/upgrade the light before getting into coral. It's fish...

bought it used a couple months ago gen 3 pro no box. 2014 model. I Went a different route with frag tank , all t5 , so now I’m selling it to recoup some cash. Can’t really tell by looking at it if it’s a pro. Looked up a few pics and it looks like it could be because it has purple lights...
