for the most part 20K is more blue than 14K while 14K most of the time has better Par.

But there are some pretty blue 14K bulbs out there. The Phoenix 14K has lots of blue

Apparently the labels that bulb manufacturers put on their bulbs (14K or 20K) often have no relationship to their actual color temperature. The Pheonix 14K for example, I've read is pretty identical to a 20K in terms of its wavelength color spikes.

Yea I have read that too but my Phoenix looks nothing like the 20k bulbs I have seen (way more white) and mine is even brand new (one would assume it would burn in whiter).

Who knows.

I tried a Pheonix 14K DE, one used for 8 months, and it was so blue/purple it was like super actinics. So it depends on your ballasts as well, what color you end up with (my ballast was EVC e-ballast)

Yea that is why I was shocked that it wasn't all that blue. I run ARO ballast and it is about the same temp as a 11k T5 bulb. I even keep my supplemental lighting on. Maybe it fades more blue... who knows. I like it (for now) so that is all that matters I suppose.
