It is the same for me. And I measure the luminance of my screen, 
lightbox and viewing lights. And profile monitor and printer with the 
Spectrocam. The point that I tried to get across is that when there's a 
difference in illumination whether in your setup in the studio or when 
the prints are in a gallery somewhere else it makes good sense to adapt 
the color temperature of the light to the amount of light. According to 
their messages many of the gurus  use the 6500K for the monitor and a 
much lower number for the lightbox etc so there's no strict rule for it. 
Based on that I presume there's a difference in
illumination too in their case. Kruithof gives the relation between the 
illumination level and preferred color temperature, it is still a wide 
band and not a single curve so there's some slack.
