Wurkkos TS21 - Technical Parameters and Specifications; Key Features and Components; Battery Compatibility

WurkkosTS21isanextremelybright,powerful,andversatileEDCflashlight,designedforhomeand
professionaluseaswellasoutdooractivitieslikecamping,hikingorfishing.Itispoweredbyasingle21700
Li‐ionrechargeablebattery.ForultimateconvenienceitcanberechargedviaUSB‐C.
TS21deliversamaximumoutputofupto3500lumens(Inthecaseof6500K,thelowerthecolor
temperaturevalue,thelowerthebrightnessvalue)withamaximumrangeof217meters.Itssideswitch
controlsallfunctions:poweron/off,batteryindicator,outputlevelandchangeofmodegroups.The
sophisticatedAndúrilUIprovidesabothuserfriendlyandhighlyflexibleinteractionaswellassimpleone‐

Notes
Theabovementionedparametersarebasedontestsaccordingtointernationalflashlight
testing standards (ANSI/NEMA FL1) using one 4000mAh 21700 Li‐ion battery in our
laboratory. Results may vary with different battery or under different environmental
conditions.Operationtemperatureisbetween0‐40°C.
