cannot be 30 feet lah. It's way too low. A cheap slave flash I used to have is stronger than this.

Range I think was abt 30 feet right? Assuming a F2.8 aperture would put the GN at 84 feet.

probably discussed elsewhere but Gain Number is not equal to coverage range. Gain number ~= Coverage range x Aperture used
