I think he's trying to point out that his 7000 lumen light is about 4 stops weaker than the Olympus GN85 strobe? That's roughly in line with my own findings that the Sea & Sea YS-D2s are 5 stops more powerful than my 14000 lumen Gates GT14 video lights.

 

Doing this test using the shutter speed is a bit counter-intuitive, because the strobe exposure isn't impacted by shutter speed. You would've gotten the same exact exposure with the strobe at F5.6-1/6-ISO200 as you did at F5.6-1/125/ISO200.

I searched for some information on this issue.

“The flash instantaneous flux of index 32 is 40 000 lux * 62 square meters = instantaneous brightness is 2.5 million lumens.”
