I am trying to find out what the light output is in terms of an f/stop @ 1/125 sec. for the Fotodiox Pro LED 312A light. I would like to know what the f/stop is at either 6 and/or 10 ft. Preferably, this figure should be based on an exposure reading taken in a dark/dim environment. The company does not provide any figures concerning this light output that I can discern.
Any help – greatly appreciated.
