You can do it with one light, two or three .. depends on what you are looking for.
Usually the three lights are for shooting where you want no shadows or you want
them minimized as much as possible. More lights at different angles helps to fill in
shadows. You can also do that with reflectors.
I think that the brightness matters more than the number of lights.
The color temp makes it easier to color correct in post processing. If you can set
the white balance in your camera, the color temp of the lamps is less important, as
the white balance will compensate for it.
For what we're doing, the most important part is getting a lot of light in there.
I shoot pens with a 500 watt work light. When I'm getting serious with larger
items, I use two 1200 watt strobes. Maybe another one above used like a hair light.
ps.. I'm no expert. Yes, the 5000 is close enough that you should have no problem
adjusting the color as you need it. That's about daylight color.
