And here's a CSG one, made like this:

#declare LightBulb=merge{
    sphere { <0, 0, 0>, 3 }
    cone { <0, 1.4553, 0>, 2.6234, <0, 2.8474, 0>, 1.8511 }
    difference {
       cylinder { <0, 2.8473, 0>, <0, 3.8176, 0>, 1.8511 }
       torus {3.6, 2 translate <0, 3.8176, 0> }
    }
    cylinder { <0, 3.8176, 0>, <0, 4.6, 0>, 1.6 }
    torus { 1.2, 0.4 translate <0, 4.6, 0> }
  // Set ambient to 1 to "turn it on", and put a light source inside it
    texture { pigment { White } finish { ambient 0.0 }  }
    no_shadow
}
