The Wurkkos TS21 is a 21700 cell flashlight using the Andúril interface. The indicating switch and triple Luminus SST-20 make it great!
I have today my very first Wurkkos flashlight, the Wurkkos HD20 21700 headlamp. It’s quite a beast, actually, offering every feature I can really think of. Dual emitters (one high CRI, one flood). USB-C charging. USB-C powerbank(!!). Magnet tailcap. It’s just really a full featured headlamp! Read on for some testing.
