i dont have alot of experience with the 150W DE bulbs, so take this with a grain of salt.

i replaced my stock 14k bulb with a phoenix 14k, and i like it.
its a nice color, slightly blue.

I havent tried a 20k bulb, though i was contemplating it.

FWIW, i think the phoenix 14k would be perfect with VHO actinics.
but because of my tank size, its not really doable, so i'm gonna try a panarama led strip for actinic supplementation, just to get a little more pop out of the color.

hope that helps.
