I have been looking for some “non-Clicky” drivers, (drivers that are controlled by a momentary-on button, simmilar to that used in many side switch lights, like Olight S20, S10, Ultrafire UF t20, etc, that runs on a voltage range of between 5 to 6 volts, has little or no parasitic drain when off, and has Hi, medium, Low and preferably moonlight/firefly and no or hidden strobes/sos/disco modes. Anyone know of a place to get such an animal ?
