I just had a conversation with a guy who's a lighting expert. He explained to me that Kelvin doesn't matter when looking for light that simulate daylight. What matters instead is CRI (Color rendering index) which is a "quantitative measure of the ability of a light source to reproduce the colors of various objects faithfully in comparison with an ideal or natural light source" (which I haven't heard or seen Mark or anyone on the forum talk about). He told me that the fact that the bulb is 5000K has nothing to do with the ability of the light source to reproduce natural colors.The light source needs to be 90-100% on the CRI scale or something like that to be eligible to see the colors like they appear in natural daylight. He told me that Kelvin didn't alter the colors, and the only thing that matters is the CRI index. He also said that 4000K and 6000K where standardized measures for daylight light sources (Mark says I think that only about 5000K is daylight, which the lighing expert I talked too disagreed with). He also told me that those 85W fluorecent bulbs would be way too powerful and emit rays all over the place and that I would need a screen (?) to direct the light to where it's needed (where my easels at). Now I'm very confused to put it mildly...
Can some please clarify???!

The whole point of the shadow box setup is to act as a screen, so there's no disagreement there either that I can see. It keeps the light that lights your easel and your palette from also lighting your setup. The important things are to use the same type of light (in this case 5000K) for both, and then follow the instructions in the video for balancing them in terms of brightness. Nothing magical about 2 85 watt bulbs. You may need more or less depending on studio size.
Also, do I have to fit the bulbs inside a lamp screen??
