Our current Godox AR400 ring flash has an output of approximately 8500 lumenseconds with an unknown flash duration. However, assuming that the same numbers apply, we have: 1.270,000 lux, or 13 times the maximum sunlight intensity for a short interval. If limited to a shutter speed of 1/200 due to a rolling shutter sensor, that number is down to 1,700,000 lumen and 280170,000 lux, or three 1.7 times the sun intensity.
