Packing photons

The creation below appeared on a blog late last week and generated some considerable interest. 

12 x 580 Speedlights controlled with RadioPoppers, firing on full power is great for turning day into night.  However some people seemed to miss the point of what this gives you, arguing that for the same price you could get a high wattage studio light.

What this set up brings to the game is high power levels when using high speed synch at very fast shutter speeds.   In a normal high speed synch mode the power output of the flash is reduced as it is essentially firing a lot of short, very fast pulses to make sure that all parts of the sensor receives the same light as the shutter curtains sweep past. 

The poster plans to use this for getting a fast enough shutter to freeze the action of dirtbikes at the same time as having enough power to properly light the subject, and turn the midday sun into mere fill light!  Can't wait to see the results.
