Joel,
        I think the issue here is that the light levels are so much more 
dependent on room reflections which predominate with a bare bulb. The room 
*is* the reflector and it varies widely in reflectivity and size.. If you 
used the flash for outdoor photography then they could give you a GN but it 
would be embarassingly low.
