You might be in another world, or the 90s perhaps?

Different settings are useful because modern flashlights use LEDs and get absurdly bright. Dimming them lets the user select an amount of light appropriate to a task, and preserve battery life. If you’re in the dark you’d want to start dim to avoid blinding yourself or annoying others (in a campground for instance). Strobes are good for getting attention.

Many of my lights use a common firmware called Anduril, which has some other nice features like a simulated candle flicker, or lightning storm (I use this for Halloween). It also allows me to turn it on directly to the lowest or highest settings, otherwise it defaults to the last level I used. There’s even an auto-shutoff feature which is nice for a night light.
