Well I did some further investigating and I found this link with everything that should be needed.

F17T8/TL741/ALTO - 368126

The color temperature (also referred to as color range?) is 41000 K. Is that good/bad/horrendous? Again, I have 6 of these set up producing 2000 lumens/sq.ft. So what's teh verdict? A good/bad spectrum?
