If I had to guess, I'd assume that all the power goes into the light, and that
you can treat the bulb as a point source and probably make the measurement off
a lambertian reflector at a measured distance...but I know I'm missing some
I think this might depend on the emissivity of the object (an emissivity
of 1.0 is an ideal black body, which I think only exists as an ideal).
So a tungsten filament is more likely a gray body.
Not sure if these would fit your needs - they're more for wavelength
