For about USD$10 including trustfire(flames) 18650 battery - it’s a great off-duty walkaround light for my military-serving boy. I am sure there’s more than a few lights out there that will also serve the same purpose. But I bought a few of these, just in case.
I’ve been really impressed by the Black Shadow .Little AAA key chain light. It’s just over the price point, but if you can get it with a coupon…only barely.
My fav is my $9 Ultrafire C8 - small enough to go in my pocket at work but bright enough to inspect the undercarriage of cars even in opposing backlight.
actual otf lumens is closer to 350-375, but still, its decently driven and has enough cooling to actually use it as a handy pocket light without cooking your hand.
It’s a compact twisty with shitty but working clip, nice design (in my opinion) and relatively good output (outshines all other low price lights from this budget class). Around 10-15lm output, nice “throw” but with rings (since very symmetrical they don’t bother me). NW tint.
