It is not really an accurate categorization and is very subjective. In practice, they are all too often more similar than different. In theory either sixspeed or Pmolan would be correct

i know its not really what you asked, BUT.........

14K tend to look like an even balance of blue and white. it looks like a 10K MH w/actinics.

20k is a deeper blue.

ive used both with no other secondary lighting (just the MH), an dhonestly i like the 20K's. but i like blue-heavy lighting
