D50 vs D65 for Color Matching Stained Glass

I am building a light box to use with color matching stained glass. Need to match sunlight. I'm considering items 4026.2F.50 or 4026.2F.65. Which would you recommend for my application?

For matching daylight, we would recommend our D65 color temperature option of the NorthLux™ 95 CRI T5 LED Linear Light Fixture. (PN4026.2F.65)

The light box where the light(s) will be installed will have a glass or plexiglass (I haven’t decided which is best to use) cover of approximately 24”L x 19”W. Would one bulb be enough or two, three?

Based on our limited experience with lightboxes, we have found that the ideal lumen output is often defined by the purpose. 

For example, a light table used for the photography of negatives might require a very high output to assist with high-quality capture, whereas you may not require as much output for your stained glass work. 

If you have a precise lumen target for your lightbox, it might be helpful to know that the 2 ft T5 Linear Light fixtures have a lumen output of 900.
