More like 10,000 times stronger... but still quite massive
"Since Jupiter has no true surface, the Jovian lightning flashes are
cloud dischargaes. Observations suggest that Jovian lightning emits, on
average, 10 to the 10 J of optical energy per flash, whereas on earth
lightning radiates only about 10 to the 6th J per flash. Estimates of
the average planetary lightning rate on Jupiter range from 0.003 per sq
km per yr to 40 per sq km per yr."
