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
4D batteries just doesn’t make sense in 2024. That was for incandescent lights, modern LEDs are brighter and use a small fraction of that power. You could still have the form factor if you really wanted a giant flashlight for self defense or something, but a pair of AA’s if you really don’t want rechargeables would be more than enough for a long life flashlight.
But any LiIon battery is going to far outperform alkaline batteries.
