The flashlight seems to be very good, unfortunately it is badly underdeveloped. Despite the well-done modes control, protection against excessive discharge of the battery and information about its condition, built-in TP4056 charger. It has one disadvantage that disqualifies it. Namely, the flashlight pill has a hole under the diode. Through which the LED which gets over 1.5A has NO COOLING. With such a current, the uncooled LED will burn very quickly during continuous lighting !!

  • thanar Does it indeed have low-voltage protection circuitry? If you leave it on, does it automatically shut down on 3V when using unprotected cells?

  • thanar Hello. Can you possibly comment on whether this flashlight has a over-discharge protection circuitry? TP4056 for charging is OK and generally works fine with any 18650 cell, but what about low-voltage cut-off?

  • thanar Hello gutekpl,I also found that there is a hole under the pill and all heat is dissipated by the pill's circumference. However, I did not measure anything above 900mA on a full cell, which translates to around 1.2A on the pill (XM-L T6 is rated up to 3A). I also noticed that the current goes down as the flashlight gets hotter, presumably the diode's internal resistance raises. That said, I don't think it will have any longevity issues due to heat.
