Advantages and disadvantages of flashlight rotary dimming

Advantages: The structure is simple and reliable, the possibility of misoperation is small, and the gear position is clear. Disadvantages: Some friends think that this method cannot be operated with one hand, it is"moron"design, it was also argued that when the head is unscrewed it affects the overall strength and contact. But in fact, there are still many tubes that need to be tightened again after the head is unscrewed to adjust the light. For example, the OLIGHT M3X in my hand, Lumintop td12, td15, td15x, etc. are all like this. I feel that this does not affect the overall Intensity. Even if it is my TK12, if you need to unscrew the head to enter the next brightness, you only need to loosen it a little bit. The rectangular thread on the head is very tightly occluded, and with the function of the O ring, it can be thrown into the light when it is unscrewed. After half an hour in the water, there is no water in the barrel.
