Fenix TK21 XM-L U2 features an intense 468 lumen beam (1 hour 50 minutes run time ), four levels of output plus strobe and a convenient side mounted mode switch for brightness/strobe selection. The highly efficient Cree XM-L U2 LED provides impressive run times at all four output levels whilst delivering a reach in excess of 200 metres, combined with powerful spill lighting to safely illuminate your surroundings.
TK21 can be powered by 2 x CR123A batteries or 1 x 18650 Li-ion rechargeable battery and offers simple operation. Switch on the light using the momentary/constant-on tail cap pushbutton, then cycle output levels using the side dimmer button. Your chosen level is memorized, meaning your the TK21 will always activate at the last used output (except strobe). Strobe mode can be quickly accessed by a continued press of the mode button.
