Underwater Camera Articles: Strobe Tests of the best underwater strobes on the market. Head to head comparisons.
The strobes are compared with and without diffusers however backscatter fails to compare at the same beam angle
So the Inon Z240 that has already a 100 degrees (you can see it drops less away from the centre) looks weaker however the reality is that the YS-D1 line with 100 diffuser should be compared to the Inon Z240 without diffuser
Inon does not have a 120 diffuser option but looks like the YS-D1 120 curve is more powerful of the Z240
Anyway an interesting but misleading comparison
