My strobes have a dial for the strength of light that is emitted, as you can see here:
The problem is that it only seems to affect the modelling lamp strength and not the strobe strength. If I set it to full power or lowest power, the modelling light changes like it should, but the strobe light always fires at full strength, no matter what.
What am I missing? The manual even says "You can adjust the brightness of the flash by turning the flash output dial clockwise for more power or counterclockwise for less power"
That seems pretty straightforward to me!
