This turns my shader into both shaders shown above, accept for the fact it does Blackbody. The first one I did gives normal Lambertian emissions light, using the default Cycles emission falloff. This one is BlackBody color based, plus the magic trick of disappearing... You can add the lightfalloff node to my original shader posted and use the other 3 types as well. And yes, there are more than 3 types of light falloff in Cycles.....
