Repairs to my house after my fire has progressed to hooking up light fixtures and selecting lights. The contracter asked, what do you want. I have to give him an answer this Friday. I use my computer room as my digital dark room and my dining room table I usually do my matting and final touches to my photographs.
Soooooo what would you guys suggest? I know I will need at least 1 pure white light for color corections. How do I describe that to a contractor??
Inputs greatly appreciated.

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.

This answer is more of what I was looking for, digging through my lighting book trying to find "lumens" there was a discusion on this in one of my text books, but haven't found what I needed. Daylight balenced is more correct term than pure white. Pure white came from my days working with lasers.
52k I think is the temperature I need, 60k comes to mind for some reason.
I don't care about cost insurance is taking care of that. No matter what they are going to screw me, so when given a choise I want the choise be a wise one.

BG is correct in saying daylight balanced is what you want. If you are using the dining room table for your work you might have a problem with esthetics vs utility. the stuff I'm most familiar with consists of daylight balanced flourecents. You might consider a floor lamp produced by Ott-Light. they are expensive but can be moved from room to room.

Er, you need 5200 K, 5500 K or 6000 K, not 52 K.
