Hi Elias -
Yes GNs are the same for lamp or strobe but they are only
estimates
and your reflector/light management device will have a
major effect on
light output...
I wanted to comment on your observation relative to light
quality from
flash lamps. Others will debate it but there is no
question in my mind
that you are correct...the quality of the light from a
"bulb" is
obviously nicer than that from a strobe. I think it has to
do with the
longer illumination times for the lamps and also possibly
color
temperature differences...

I meant to comment on this. I also find a difference in
quality. I think it has more to do with the size of the
light source but it may be something else. There should not
be too much difference between a blue flash bulb and a
strobe although the stobe may be bluer.
Flash powder, used in trays, had even softer light
because the source was pretty extended.
