Question: lighting effects

[Vikinger]

I think he mean the light that is illuminated on nearby surfaces around the explosions.
Like in this picture where you can se the trees lights up to the right in the explosion light.



Edit/ Read the above posters a bit wrong. And yes maybe the starshells illuminating halo effect cud be the key. But how to link or create that effect to the explosion is beyond my knowleadge.
