Oh, speaking of which, my LuxPro 4×AAA light also has one of those soft-touch e-switches in the tailcap. Can’t for the life of me undo the ring that’s around the pogo stick, but just bridging negative to the tube gives 100% brightness. “100%” through the switch still has some pwm “notches”, which is how it powers the tailcap’s driver.

You always gotta be VERY careful with series alkaleaks, else eventually they’ll for sure ruin the innards of the carrier and light itself if you let ’em. Easy to get 3×AAA carriers (long and short), but try getting a 4×AAA one.
