Measured my old Ultra 1200's with a color temp meter. They show 4,980, 5,120 K over the power range. They also have one of the UV tubes (i.e. Ones sold in the 1990's for Ektachrome film.) in the head along with one clear one. Color hasn't been problematic and I prefer the warmer look. Maybe with both clears they would be 5,300 K or so, but not a big deal.
However, one a Nikon SB-900 it is really blue and measured at 6,100 K. An older Vivitar 285 was close to 5,200 K but it has a yellowish window too where the Nikon is clear.
I was curious though that as these things age, what happens to the color temperature from the tube? Does it warm or cool?
Tia.
