Light For Grading

What type of light do you use for grading, and why?
According to HRH, the PCGS graders use 75W, frosted incandescent light (see Q&A)
My preference is a halogen light source because I find it is the best for seeing underneath toning. At shows I usually use incandescent, because that is what is available.

but if you come to my table at a show I will have at least 2 100 watt Reveal bulbs that I will use. I hate coin show lighting.
