Well, if you are using a light that is adjustable in color temperature it should be enough setting the temperature of the color balance in the image to fit the light.
You should not need the light in the holes.
You can make a first photo in the session just with the light (no film) without clipping the light and messure in it the temperature and tint to use.
You can do that with any other source of light as long as it emits a stable light.
As you have used the 80D, you should use its colro matrix interpretation as input profile, if what you want is reproduce the colors in the negative.
The negatives have a strong color cast (usually orange in color negatives).
Negadoctor inverts colors and eliminates the color cast.
I think that the radiactive greens come from not properly eliminating the color cast or the cast being too strong in your negative.
