Digital BW, The Print

On the colorsync list quite a number of color gurus use 6500K on the 
monitor and 5000-5500K on the lightbox etc. I have done that for some 
time but switched back to 5000K for all. But I use 5000 with 2.2 Gamma 
and not the 1.8 usually associated with 5000K. The Prove It! software 
needs a bit more custom settings for that. The moderate quality of my 
monitor probably has to do with the lower preferred setting, it lost a 
bit of its output. When the room isn't too light it doesn't matter. 
Using 6500K for the monitor versus 5000K for the lightbox isn't so 
strange. The amount of illumination influences what is considered the 
best color temperature for viewing art etc. So quoting color temperature 
and not mentioning lumen or footcandles for the same source doesn't help.

In that chart 5000 and 6500 are not that far apart and near the center 
of the curve. Footcandles a factor 2:3. You can put them next to one 
another.
