Combo: NITECORE E4K Compact EDC Flashlight - 4400 Lumens -1x NITECORE 21700 Battery Included  
w/Nitecore UT32 Dual Emitter Headlamp -1100 Lumens 

Equipped with 4 x CREE XP-L2 V6 LEDs with a lifespan of 50,000 hours, the NITECORE E4K is able to emit a blazing output of 4,400 lumens from a palm sized body with a max peak beam intensity of 11,100cd and a max throw of 211 meters, ideal for EDC (Everyday Carry), trekking, camping and more. The independently controlled quadruple LEDs are powered by a constant current circuit to provide a durable usage with guaranteed safety.

The ultra compact and lightweight body of the E4K provides convenient and flexible usage and is constructed with a CNC machined unibody design, featuring lightweight, solidity and excellent heat dissipation. The anti-skid knurling is ideal for long term carry or operation. The cooling fins are designed to reduce weight and enable quick heat dissipation. The tail stand capability offers hands-free operation to be placed on a flat surface.

With the NL2150HPR battery (5,000mAh) included, the E4K is recommended to be powered by 1 x 21700 battery (discharge current over 15A) while compatible with 2 x CR123 / RCR123 batteries. It provides 700 hours ultra long runtime for a consistent usage of 30 days on ULTRALOW. The integrated ATR technology regulates the output of the E4K according to the working condition and ambient environment to maintain the optimal performance.

Specially designed for outdoor applications, the one hand operable side switch of the E4K has a wearproof silicone cover which is friendly for glove users. With 5 brightness levels, 3 special modes and dual user modes available to offer direct access to TURBO/STROBE, it serves as your best lighting tool for multiple scenarios.

You can be easily informed of the power level with the patented power indicator. The included two-way clip also enables additional carrying ways to be clipped in the pocket, the backpack or the belt.
