Well, I modeled a bulb with a filament, and it looks ok in the include file
render.  Replacing the point light sources with these bulbs gives me --- eeek.


Here's my lampshade glass:

  //  Glass
  difference {
   cone {<0, 0, 0>, 1.95, <0, 4.625, 0>, 3.875}
   cone {<0, 0, 0>, 1.95, <0, 4.625, 0>, 3.875 scale <0.9, 1.2, 0.9>}
   translate < 7.687, 0.4375, 0>
   interior {ior 1.5}
   texture {pigment {rgbt <1, 0.7, 0, 0.9>} finish {emission 0.7}}
   double_illuminate
   }
