Thanks Bill, I had skimmed over that document but missed the light reading (which surprised me). Any tips on targeting light levels less than this?

I'm not sure about how to reply to your quiestion, but have done a bit of research. The CIE viewing conditions are met by various [a href=\"http://www.inkjetmall.com/store/cm/gti.html]Viewing Booths[/url].
In his color management book, Bruce Fraser says that for monitor to print matching, the brightness of a sheet of paper under the viewing conditions should be similar to that of the white on the monitor. He does not bother to match the color temperatures of the monitor and viewer, but suggests that they should not be in the same field of view.
I am not trained in photometry, but will give the following analysis of my current setup for comment.
With my own setup, the monitor (an LCD) is at its native white point (probably about 6500K) and with a calibrated luminance of 140 cd/m^2.
My old Gossen Luna Pro F has a table on the back of the meter for use with the incident light diffuser. With the meter set to DIN 18 (ISO 50), a reading of EV 5 corresponds to 175 lux, EV 6 350 lux, and EV 7 700 lux. Using this table, My Solux 5000K light at 2 feet gives about 500 lux according to the meter. If white paper reflects 90% of the incident light in a Lambertian fashion, I think the luminance for this amount of illumination would be 500 * 0.9 / pi or about 143 cd/m^2. In practice this seems to work out well, but I welcome comments.
As a rough check, I used the reflected light capability of the meter and took a reading from the screen and the paper, and the readings were EV 8.5 from the screen and EV 9 from the paper with ISO set at 50.
