12 Gallon 150w Lighting Options 14k or 20k

[Bmgrocks]

Well, its time to upgrade my lighting, I'm using a Current Sunpod 150w Fixture. I've had my Pheonix 14k for a while now, and I'm looking to changing my bulb. Great color, but I'm curious about 20k options....I really enjoy the look of heavy actinic supplements, without having to retro fit, some actinic T-5's to the Sunpod

I guess my question is What is your experience with 20k bulbs, Brand's, color preference, and coral Growth.

My tank is mostly Zoa's and I'm sure they will look pretty neat under heavy actinic saturation. I'm not as concerned with growth anymore, the tank is up and running, stable, and I'm satisfied with its progress..

Here is a very dated year old pic, of the tank with the Pheonix 14k, still quite blue.

I got a 150 viper last night. came with a 14k and a spare. Im going to change to a 20k as well. i had them on my 180 setup and LOVED it. Excellent growth too.

20K in all of my fixtures... XMs are more blue, Radium has a beautiful 20K that I find is a bit white for my tastes... In all cases I do supplement with T5 Geisman True Blue bulbs.

So which 20k bulb provides the Best Growth?
Not necessarily a huge factor, but i do want to adequately provide for my corals
