Based on Halfdan´s example, one should now try to
artdirect the result a bit, e.g. finetune the effect.
*Extend the lit area (coming from the yellow ring)
by factor four without having the hot area blow out.
You´ll likely try to simply scale the entire scene to
extend the area mR uses internally to optimize
FG point distribution but will still end up with
blown out hotspots near the source. After some
fiddling and maybe even some FG map tonemapping
you´ll get close but won´t be able to say for sure if
the illumination radius has been exactly scaled by four.
And neither will your client!
If someone asked me to do this I would render a mask for the ring, tune
the illumination radius to taste, render the whole thing in floating
point, and bring down the ring in the post (in float).
