If you want to do true outdoor nature photography (Birds, Insects, etc.) you cannot get away with underpowered solutions like coupling together commercial units and stopping their power right down to get high speed. The plain fact is you need a purpose-built high-power unit.

It has been stated that you don't need HSF units as fast as these to photograph birds in flight but this is fundamentally incorrect! You may be lucky with larger birds, with their wings in the right position (end of stroke) to get a reasonable looking shot - but what about smaller birds, and the fine detail? By the fine detail we mean being able to resolve feather detail in a fast moving small bird. You might just about freeze the wings if you are lucky - but you will not resolve fine feather detail as this will get washed out completely by the bird's motion.

 A single unit gives out 150Joules of light per pulse with a pulse duration of 1/20,000 second. Wildlife photographers normally use three of these units synchronised together.
