Nitecore

E4K E4K

A compact powerhouse that fits 4,400 lumens into a package small enough for everyday pocket carry. The E4K uses four CREE XP-L2 V6 LEDs behind a quad-reflector to produce a massive flood of light with a 211-meter throw. The single side switch handles all operations including lockout, and USB-C charging means you can top off from any cable. The aggressive knurling and HA-III hard-anodized finish give it a tactical feel without the tactical size. If you want maximum brightness in minimum space, this is the one.
