I'll try it ans see what it does.

Actually, media_attenuation was specifed as on, but I think that was a type,
as I think I meant to have it off. I think I need to have the light fade out
stringer than it currently does. Hopefully that will fix it. Right now the
end is brighter becasuse as the spotlight's cone widens, more and more of
the media gets illuminated. Strengthening the fading and adding the
absorption to  media will hopefully help.

I would tend to vote on the volume aspect. Maybe if I add a point light
source with very strong fading it would help a bit?
