Interesting. I found some drivers and bulbs for xenon strobes while looking for garden/yard security lights (long, tangential story).
My back of the envelope calculations are as follows:
Aviator LED strobe:
65J/0.05sec = 1300W
1300W*100lm/W = 130,000lm
130,000lm for 0.05 sec = 6500lm/sec.
Xenon strobe data is more tricky, I found a post on CPF estimating a 50j Nikon SB800 strobe produced approximately 1.4 million lumens.
I was looking at a kit to drive a 200j xenon bulb for (guessing) 0.002 seconds(?).
200j/0.002s = 100000w
100000w*30lm/W = 3million lm.
3million lm for 0.002 seconds = 6000lm/sec.
Can anyone confirm/correct the above?
