A related side question here, since lights were mentioned. I know that 6500K is a frequently recommended temperature for the monitor, yet for proofing prints, a lot of people also recommend the Solux lights at 4700K. That seems like a mismatch to me but I confess I don't understand a whole lot about this whole color management thing yet.
Unless you are preparing prints for a gallery or an exhibit I would stick to 6500°K. As Hal mentioned this is equivalent to the average color temperature of daylight on a sunny day in late morning. This is the most acceptable of all compromises for any given situation.
Prints that are to be displayed in very controlled and specific lighting conditions should be printed using a monitor that is set to the same color temperature as the lighting that will be used in the exhibit. That way there are no surprises when 50 prints are prepared for display and they end up looking skewed under the gallery directional lighting.
4700°K is close to incandescent lighting and that is why the Solux lights are recommended. This is fine since the eye can compensate when it sees a print under that color lighting while comparing it to the image on the monitor display set to 6500°K.

Yes I tried 6500K this weekend with 2.2 Gamma. I also used my new printer an Epson 3880. It all came together and I would say color management is working very well for me. No surprises and my soft proofing was spot on to the finished print.
