Count. The smaller your sources of "light" are, the higher count you
need to use to ensure that the surfaces you're illuminating don't have
their random radiosity-testing rays spinning off into empty space, and a
lightbulb is very small indeed.

In fact, I would even suggest that you NOT attempt this. When I tried
it, I found that even increasing count to the max didn't provide results
that were acceptably smooth. Instead, use a normal light (perhaps with
fading) for your lightbulb, and then apply radiosity to that scene..
that way, a much larger part of the scene will already be lit, and
radiosity will be far more effective.
