Nitecore TM20K - 20,000 lumens - CREE XP-L2 LEDs - 21700 x2

  • 29995

Constructed with two 4800mAh 21700 batteries installed, the TM20K shoots the namesake 20,000 lumens out to 290 meters. Accessing it needs the use of one of the switches between the metal power button and USB-C charging port, which also activates the Strobe function. The power button cycles through the standard modes, plus spot- and floodlight modes for focused applications of the LEDs.
