You should specify the bulbs that you want used; that's the easiest way. I haven't done much research on this lately, but there are "daylight" balanced bulbs in lots of form factors (screw-base, fluorescent tubes, compact fluorescent, etc.) You said "pure white light" for color correcting, but I don't think I understand what you mean by that. "White" light doesn't occur much in nature. Sunlight is warm (more red), unless it's overcast (more blue). Interior lighting is usually very warm (incandescent bulbs). So color correcting to some artificial "pure white" may not produce the result you'd like...since that light won't exist anywhere else.
The shortest answer is to say that you want daylight balanced bulbs everywhere. They'll be more expensive, but they look the most like sunlight.
