( I personally disagree - both solutions are just kludges, and both have
disadvantages. My personal preference is to set ambient_light to some
very low value when using radiosity - e.g. 0.001 - and set ambient to a
correspondingly high value - in this case 1000 - for objects that should
appear to be glowing (again, only when using radiosity).
The /really/ best way to do it, however, would be to patch POV-Ray so
that object "glow" could be modeled without misusing the classic ambient
mechanism. )
