Cheap SK68 clone with angry blue knockoff or unknown brand emitter, attached with single use press fit sheet retaining ring in a hollow pill, and powered with a boost driver which resorts to resistor limited current when operating with input voltage higher than emitter's Vf. The onboard current sense resistor is used for sensing when in boost mode and to limit current when high input voltage (when fed with li-ion cell, for example). 
My advice is: if you like it, keep using it with Ni-MH cells. Unless you are a skilled and talented flashlight modder who knows what and how do not waste your time with such wrecked by design ignominy.
Good luck in any case.
Cheers :-)
