Its biggest advantage is that no frequency can be seen in any mode, and there is temperature management.

It can control the flashlight temperature not to exceed 55 degrees Celsius,

If the flashlight temperature is below 55 degrees Celsius, it will output full current. If it is above 55 degrees Celsius, it will constantly adjust the current so that the flashlight will not overheat.
