My understanding of the lamp I was using turned out to be incorrect in that it essentially had more that one lampshade.  With that knowledge on the lamp and I changed the settings leaving the blackbody at 2800 and the LightFalloff set to Quadratic, but the emissions strength set to 10 to account for the fact there is now light coming thorough the lamp shade. 

and again with post work.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
