Thank you indeed Robert :-)

The pavement is made of individual stones (some 20k+ of them) using my 
Cobblestone macro. They are aligned on an irregular surface (could be 
increased some more) and have some irregularities in their placement. Each 
stone has its own random texture variation of course. So, I am not sure how 
to implement your suggestion here, but I shall think about it.

OK, this is the crux of my trials and errors. At the lamp locations are two 
spherical emission media with spherical densities. What I did however, and 
maybe I should attenuate that, I shifted the center of the density some way 
up. My intention was to deform the halo a bit like one seems to notice in 
the original: the halo is stronger below the lamp shade than above it. 
However this causes this sharp boundary you mention.
In addition, a scattering media scatters the light cone a bit further.

Again, thank you Robert.
