i found that the keyword extinction in the media statment can make a
huge difference.. try:

  media {
       scattering {1, Gray50 extinction 0.0 }
        }

this creates an effect similar to emission, but only where the spotlight
is, which is a good effect.. i used that media in an image of a sword
backlite by a spotlight.
