well I got my bulbs yesterday from sun aquatics so I was fooling around all evening testing them out. the 10K's are pretty crisp looking, the 14K are real blue (radium type of blue) and the 20K are real close to the 14K bulbs but with a hint of purple. In all fairness I am going to compare them all again in 3 weeks after I have let them break in and do the initial color shift, at this time I will measure the PAR from each bulb.
the first pic is a 2 year old AB for a starting referance
this is the brand new 10K SA bulb
this is the 14K SA bulb
and this is the 20K bulb
now remember this was the first time they were flashed, I expect the 10K to whiten up a little and hopefully the 14K will also. this is why I want to break them in for a week and do this again.
