I like vibrant color in my tanks. The pink tubes (Actinic White) combined with Actinic do it for me.
I am very familiar with the 12,000K/Super Actinic also known as Actinic White/Super Actinic but the 14,000K/SuperActinic could be worth checking out. Too bad they don't have photos.
Here is a pic of the competitor product, the Helios brand "Ultra Grow" bulb from Commodity Axis. Unfortunately, it does not have the internal reflector design of the UV Lighting tubes offered at ReefGeek.
The fascinating thing about this blue-pink color combo is that together it reflects a white light that accentuates the reds, blues, greens and yellows.
I really don't understand why the PC tube color combo below seems to be so popular. IMO the color reflection from white-blue tends to appear washed out:
