For consistent flash energy, flash durations can be substantially shorter using broncolor cut-off technology than is possible with conventional units:
Comparison without broncolor cut-off technology
t 0.5 does not measure all light relevant for the complete shooting: light is radiated before and after t 0.5, which can result in blurring.
Comparison with broncolor cut-off technology
The total quantity of light is taken into account. No blurring, because the flash is cut off.
t 0.1 = 1/600 s
t 0.5 = 1/600 s
Good to know
There is no generally valid factor for converting t 0.5 to t 0.1. It is therefore not correct to use t 0.5 to compare different flash durations; for comparisons t 0.1 must be known as well.
