Radion vs. AI Sol

[Borderjumper]

I have two Radions over my 48" tank and love them I've never seen a SOL, so I can't compare them or really comment.

I have been thinking of going LED over my 16" cube tank.. I'm actually considering one SOL as I think a radion is overkill for that small of a tank.

Looking at Ocean Aquatics webpage, it looks like the SOL comes in two color choices.. The white which is 12-14K and the blue which is 20k.. What are people using? And am I correct that the K color can not be adjusted to suite your eye?
How about intensity? Can that be adjusted?
