I looked at your code, and you should really consider using the macro I
posted in the "sphere_sweep woes" thread. Your lamp would render in a few
seconds. Sphere_sweep is capable of things which your lamp doesn't need, so
it's really too much tool for the job.

If you are bounding by hand then check the messages for the "Unnecessary
bounding object removed" warning. If you get this then the -UR command line
option will stop this from happening. Alternatively use Remove_Bounds=false
