I found an answer!
24 pack for $40. That's $1.67 each, including batteries. (or 6/$16, $/2.67 each)
300 lumens, single mode, AA battery, cheap, bright enough.
At less than $2 each, I'll put one in every drawer and pocket and give them away at the range.
I'm only kinda joking. 300 lumens really is plenty for 99% of anything I use a flashlight for.
I'd pay four times much if there was a 15/50/100/300 lumen switch on it that
wasn't the power switch. When you need just a little light, just enough to not fall in a hole, like if you're doing nighttime stuff with other people and don't want to ruin your or their vision, even 200 lumens is way too much.
