        Isn't there a way to do this using a 35mm camera
and calculating it with the built in light meter? Does
anyone know how to do this (from what I remember, there's
a couple of ways with minor conversions, etc.). Thanks
for the info Perry, that explains why incandescents of
low wattage seem brighter (or at least to my eyes!).

        Hey, I just realized that with what you're saying, the
light I described could be low output but high energy consumption!
Geez, no wonder they keep us in the dark about these things ;-)!
