About this super FP thing. Apart from the battery power supply
problem I would have thought - given the colour 'temperature' that
flash tubes operate at - that a major impediment to increasing the
output would be overheating of the flash tube.
You might need a gattling gun arrangement with multiple tubes fired
alternately so that none get too hot.
I once saw a TV program about a very powerful portable spot light.
It used a zenon flash tube firing at 60 Hz, or whatever, so it
appeared to the human eye as a continuous light source. The flash
tube was liquid cooled, pump and all, possibly with freon (this was a
few years back) The program showed someone reading a newspaper by
the light of the lamp - from a mile away.
