Flashlights that use the open source Anduril v2 interface are… tolerable, I’d say. It’s not good, it’s not intuitive, but it does at least make it easy to just turn the damn flashlight on and off.

1. Click once to turn it on, once to turn it off
   • While it’s on, hold the button down to change the brightness
2. Click twice quickly to put it in turbo mode, click twice quickly to take it out of turbo mode. One click turns the light off
3. Click twice and hold your second click to turn the light on in turbo mode. Once you let go of the button, the light turns off. I actually really like this mode
4. Strobe is three clicks, but it’s not the discotheque-ass crazy strobe, it’s usually an SOS pattern. One click turns it off
5. Click four times to lock the flashlight. This stops it from turning on in your pocket. This is a big deal for some flashlights because they’re bright/hot enough to burn you if left on in an enclosed space. Four clicks takes it out of lock mode

The interface gets way more complicated after that, but I don’t bother with any of that shit. Luckily, it’s hard to accidentally activate the crazy bullshit.

There are also lights that mimic this pattern, but differ in a few key ways. The Wurkkos FC11 is a great option that’s relatively cheap. The 4000 K version is $35 and is bright with a nice neutral color temperature (I find it much easier on the eyes.) It follows the interface rules I outlined above except that it’s missing number 3 and the strobe is of the flashy hold-a-rave variety. Still, you have to specifically press the button 3 times in a row pretty quickly to trigger it. I never have accidental raves with mine.
