>>377060press 'on/off' once, and it'll turn on to whatever was the last mode it used.
Press mode while on to cycle through Low/Med/High.
Long-press on/off(when off) to turn on Turbo mode(which is ~320lumens), and press mode while in turbo to use strobe.
Long-press mode(while off) to turn the blinking red LED to a solid red LED(Only like 0.5 lumens, but perfect for reading a map in moonlight)
I'm really happy with it.
I also bought a Rofis J20, which is essentially the same flashlight(same UI, emitter, battery), but without a blinking red LED, and an articulating head(to go from 180 to a 90 degree angle light) Might be more useful if you want something to clip onto a belt or backpack strap to keep both hands free.
The biggest selling point for both these lights, imo, was the super-low modes that offer 300+ hours of life. Amazing if you're in a shitty situation and need to ration your resources.(Since lets be honest, once your eyes adjust, you dont *need* more than 15 lumens to sort yourself out in the night if you're staying in one spot.)
