Joan,
The 1000bulb site 23 watt bulbs are only 2700K and will be very biased to the red. I would recommend 5500K fullspectrum bulbs from Sunwave which have a CRI of 93. I use 4 of these bulbs in my overhead fan light for when I want a lot of light in the studio. Two or three would probably all you would need for your work.
