but can my flashlight run QMK
This vendor carries a lot of high value-for-money flashlights and also sells tool you would need to do firmware flashing on their newer models, which is cool I have an older model that has different pin layout. (But also I don't truly have an urgent need to actually update the firmware on it, it works fine.)
They have a ton of different LED options, and some of the lights now even come with multiple channels to control groups of different emitters separately, or to mix the output of two emitter groups to control tint, which is wild.
More interesting to me is that they now include an option to use a confusingly named "boost driver" which lowers the max output but increases efficiency and runtime, which is something that is lacking on enthusiast flashlights, most of which show an exponential drop in light output over less than a minute of runtime. (Because the goal is to hit the highest possible output number regardless of how short a runtime is practical with it.)
Caveat: if you aren't familiar with enthusiast flashlights, they can be hazardous if you're not careful since you're running high capacity batteries very hard and also the temps can get extreme. So be careful if you do get a light like this.
