Nice to know I have brightness if I need it.
Runtime per mode
700 lumen = 1.75hrs
400 = 3hrs
200 = 6.75hrs
50 lumen with flash = 22hrs (Driver Alert Mode)
Strobe = 45hrs (Emergency Mode)
Let the battery warm up some before you charge it. The cold affects the recharging, and it works better if the battery has warmed up before you recharge it.
