Rotary dimming: It has a simple and reliable structure, with little possibility of misoperation and clear gear positions. However, some people think it cannot be operated with one hand.
Tail-press dimming: It is simple to operate and low in cost, but the strength of the tail switch is the biggest problem. Especially under the development trend of large current and high power, the instantaneous current of the switch is getting larger and larger, which will gradually shorten the service life of the tail switch and increase the damage rate. Moreover, there is sometimes the possibility of misoperation.
Magnetic ring dimming: It is simple to operate and can adjust the light in both forward and reverse directions, but it is not very convenient to operate with one hand.
Button dimming: It is simple to operate; pressing once adjusts one gear, with four gears in a cycle. Long-pressing the button enters the hidden strobe mode. It is also convenient to adjust the light when wearing gloves in winter, but the service life of the button is not clear.
