Lumen Wars

The Lumen Wars drag on, with 20K lumen flashlights eligible for 3-day shipping on Amazon Prime and the maker of a 90K lumen flashlight admitting "This device isn't very practical for most uses because it just blinds you if you're shining it at anything closer than about 100 feet."

Charge your batteries and walk with us through across the battlefield, where falsely-advertised run times are the norm, unbalanced batteries catch fire, and a clutch of makers ask "What if there's a better way?"

Open your mind, then press play.
