I see now what you mean. I have a good visual image of your problem, because I
do volunteer lighting at a local community theater. The 'beam spread' is spread
out and very fuzzy, almost non-distinct, when a diffusion gel or two is placed
in front of the light. It's almost as if there are *two* spotlights--one with a
fuzzy though not-too-spread out beam, the other with a much wider and fuzzier
beam. Yours is a good question (I wish I had an answer for you at present.)
I'll be curious to know what is suggested here, because I'd like to plug it
into my own POV-Ray 'theater lighting' scene, which I use from time to time.
