I searched the web round and round but the closest I found for HX-1101A is a picture from member keltex78 of an HX-1170A here
Five mode h/m/l/strobe/sos xml-t6. Uses one 18650 getting between like 2.10 and 2.56 (cell dependent); recently measured 2.96A with 2xCR123a’s. Features low voltage/blink warning.
Driver features chips such as XORB48, R120 and yellow component (capacitor?) says 226J.
It’s supposed to be ok with that power according to the English site specs (but not the Chinese advert) I don’t run multiple 123’s so only short-term tested consistent with what I read in English.
Old Ultrafire P10 has (had) hx-1101 driver, however I was never able to find a source for these excellent drivers. From my old testing booklet it has PWM of 7.8kHz and with single 18650 it drives XP-G at 1,35/0,82/0,29 A + 5Hz strobe
This is for version with single fet (with place for one more on pcb)
Perhaps best driver of it’s time when other drivers were using very low PWM frequencies…
