That is one tack - but control is probably more complex - but hence my
question re user experience. Light runs in 50-100 V range and
"electronic ballast" from 12V is a boost smps and current regulator.
Varying 12v should probably not affect output in a controllable
manner. Controller is doable enough but also nasty enough to avoid if
possible. 25 kV strike would be nice to allow hot start. Few do this.

Light must be regulated to standard level. This will probably lead to
a modest number of copies being made - not quite one off.

LED control is easier. Heat management OK but harder.
