In the rendered image, I had been using a finish emission on the actual glass
bulb, rather than creating a hollow sphere with an emitting media.  I switched
that out and recreated the bulb to separate the containing glass ball from the
light using media, and after fixing my radiosity settings to take media into
account, it looks much better.  Thanks for the suggestion...
