Sometimes there's nothing to do on long winter nights around the campfire except compare flashlights. It's pretty much a guy thing, like comparing certain other cylindrical objects we hold dear.
"Look at mine. Five-hundred lumens."
"That's nothing. Mine is 850 lumens."
Then I whip out my foot long Bushnell. "Twelve-hundred eye-scorching lumens, amigos." There's awed, envy-laden silence.
Well, the lumen war keeps escalating. Now there's a flashlight bright enough and hot enough to start fires or use as a stove. A guy needs to have one, or he'll be considered laughably impotent.
