Lemmy needs a community dedicated to pointless debate over which flashlight is best. I'm about to permanently borrow somebody's ThruNite T1 but it's too heavy, I miss the mini Maglite I used to carry. Phone flash is fine, yes, but I miss a flashlight/torch without a fucking login procedure involved for fuck sake.
Just grab any of the single 18650 lights. Emisar D4V2, Zebralight, Lumintop, or any other brand. Some are better than others and there are advantages and disadvantages to each brand/model but they're all awesome.
