The article that I linked has shots taken with Retra Pro and SUPE D-MAX, both at full power, in the same conditions - on a tripod, underwater. The shot taken with the Retra Pro is approximately 0.2 stops brighter in the center, with a more diffuse beam to boot. This shows that SUPE's claims of 250 watt-seconds for their strobe (compared to Retra's 150 watt-seconds) are utter garbage.

It can drive one batty trying to compare lumens to watts, or GN to watt seconds versus coverage distribution and consistency with marketing spin to boot.   And then there's the misery in (esp S&S strobes) getting the right fiber cord to couple to the SLR or flash trigger.
