  The problem is that since your bright object is small, the rays sent
from each intersection point will hit it only rarely. This means that only
few of these points will be illuminated by that bright object while the
others are dark. This is what causes the splotchiness.

  You'll get a lot better result if you make that bright object shadowless
and add a light_source (possibly an area_light) in the middle of it.
