Ultron Favia - Best PAR for bright colors?

[SliceGolfer]

Greetings all. Was curious for those who have Ultron Favia in their tank, what PAR has worked best to keep those bright yellow, red, and blue colors? Mine has been in my tank for about 6 months and has lost most of the red ring. This pic is shortly after I got it.

I think its less about the par and more about the spectrum. To get those fluorescent colors youll want a heavy blue spectrum.
