The standards would say 6500K in Europe yet Heidelberg moved their Lab space
to D50 as that's the accepted standard for PCS. I've got two Just 5000 and
another Italian 5000K. In the end the actual proposed white point only
describes a spectral energy distribution that coincides at a white of XK.
The colors derived from fluorescence however vary greatly from tube to tube
even with the suggested K value. I find that most light boxes that are 5000K
actual visually appear in tune to a D65 monitor calibration. Monitor
calibration at D50 seems yellow to me and many others eyes compared to the
light boxes. The D65 tubes peak out more blue and blue green making them in
my opinion unsuitable for previewing and soft proofing on a D65 cal screen.
Certainly there is a difference on press sheets viewed on D65 light boxes
compared to 'standard' D50 boxes. A very easy reminder that all fluo tubes
don't reproduce daylight is to shoot an transparency with the light box.
