I am trying to use the KISS method, how about this as a texture on a cone
with a spot aligned inside it?

#declare Cone_Light =
   material  // Cone Light
   {
      texture
      {
         pigment
         {
            color rgbt <0.501961, 1.0, 1.0, 0.968733>
         }
         finish
         {
            ambient 1.0
            diffuse 1.0
            specular 0.007167
            roughness 0.654133
         }
      }
   }
