You will probably have to wait a while to get them if you want to play with them. Mouser says they will get 40 in April and they are 9 week lead time.
Also noticed from the specs they run at 70 volts. So to use them in an airplane you will need a power supply.
Did some quick math on the Trustfire light. It looks like they are only driving the LEDs at 1.5 amps which is half their max rating.
From the measurements, at 13.8 volts they draw 1.25 amps
that is 17.25 watts going in.
these drivers have about 90% efficiency
so that means 15.525 W delivered to the LEDs.
the XMLs have a forward voltage of 3.3v , so they are in series give us 9.9v
that means they are getting 1.5 amps
They probably are under driving them because of the heat.
