Jason:
Standard photographic viewing light is 5000 degrees K.
The lamps are florescent
Several companies, including MacBeth and Graphic Lite sell such lamps that 
fit into viewing booths used by production departments of ad agencies and 
printers and some photographers. They are standard lengths so you could make 
your own overhead viewing luminaire lightsource.
I check and see who carries the lamps here in Dallas.
