The Godox AD-B2 has been dreamt of ever since the AD200 was announced a few months ago. It wasn’t much of a stretch to assume Godox would release something like this given the H1200B extension head. The head lets you plug in a pair of AD600 lights to get 1200Ws of power. The AD-B2 essentially does the same thing for the AD200, letting you double up the power.
According to this review from photographer Rob Hall, though, not quite. When one compares a single AD200 in the standard S-Fit adapter to a pair of AD200 in the AD-B2, one expects there to be a stop of difference (double the power). Robert’s observations yield quite a substantial increase over that. And it’s all down to a very simple difference in design.
