Thanks for the advice ToyKeeper. I was about to buy one as my very first 18650 and Anduril flashlight, so I'll have to choose another model.
According to this Master List the Astrolux S1 should be available with the Anduril UI, but when I follow the link I see a 4/7 modes one on BG – like on other Chinese seller websites – not Anduril.
Is an Anduril Astrolux S1 / BLF A6 available somewhere? I'm specially interested in the latest Anduril version, which adds the manual memory: a fantastic addition as it allows instant access from OFF to #1 Floor, #2 your favorite brightness of choice, #3 Ceiling and #4 Strobe. Which lights have this manual memory?
