"ONLY" $1800 ? ..... well, if you have so much money, feel free to gift a bit to us, too .....
j/k
But, seriously, have you seen in the draw what type of lamp is used ?
it's not a HID, it's a ultra high pressure continuous arc xenon flashlamp !!
like these ones, as example:
Xenon Lamps, Hamamatsu
Those lamps are used in scientific instruments, and costs a lot, both the lamp and the elevator / ballast ..... and are fragile during work, much more dangerous than halide HID, considering that usually they works around 250 to 300 atmosphere pressures, so i bet this guy use it
very very cautious, and not as anyone can use a normal flashlight (after all, also not speaking about the danger of explosion, waste 1000$ or more of lamp for let it drop, isn't a so good deal
)
But have to admit, from a handheld unit, it's an impressive beam
