This certainly does the job I wanted to darken the part where both light sources

illuminate.

But do you know the answer to my second question?

Is there a way to define maximum amount of brightness of an object?

I guess I'll just have to use diffuse, but I was wondering if I can just

set a cap instead of using things that'll make it darker at a rate.

Thanks for the solution by the way.
