once a year I email my favorite flashlight manufacturer to ask if they’ve finally made a flashlight that just turns on and off when you push the button, and every year they’re like, “no, but thanks so much for your feedback!”
be honest, have any of you ever used the flashing feature on your flashlight? did it actually come in handy? handy enough that I have to scroll past it every single time I want to turn my flashlight on or off
It is basically I/O limitations, and the majority of lights in this area likely have an origin in cycling lights as far as the silicon is concerned. I think that is the original high profit niche that drove a custom asic for the application of a PWM LED controller with integrated charging. Pretty much all other lights are built to a price. The chip likely has additional functionality but the actual designs are all built to a bare minimum price (or max profit margin). From this perspective, you’ll see a lot of the feature set differently. On a bike, one button is convenient as well. They usually fash too bright because of the default clock speed of the chip and a design that does not deviate from the chip’s example implementation.
