Girixd the best we can do is put a samsung 30t in it, that can easily deliver 62 amps of current for short bursts (enough to impress) but the driver and pcb traces are a current limiting factor here. though I believe samsung 30t is still the best choice for this flashlight as it can sustain 35amperes.

Girixd I am pretty sure it's what is written on gripper itself.

Girixd if you know a thing or two about flashlights, you need to be a moron to believe that this flashlight costs 60$.

Girixd it takes more than 0.25 amps input. more like 2-3 amps at 230v .

Girixd check if the fan is broken. if it is , replace the fan. Nost common fault which triggers the safety circuits in the supply. short circuit and overload can also cause this.

Girixd the Samsung 30T would perform better than 40T. it will make it brighter . total runtime will be less though

Girixd a high drain 18650 like vtc6 can perform better than 26650 in terms of brightness and range.
