Featuring a powerful maximum output of 4000 lumens, up to 350 hours of runtime, and one-touch strobe activation in every setting, the Nitecore P20iX Rechargeable Tactical LED Flashlight is a versatile everyday-carry tool for law enforcement, security, and military professionals. The light is equipped with four Cree XP-L2 V6 LEDs, and the low-power setting of 2 lumens will run as long as 350 hours on a fresh charge. The high-capacity 5000mAh 21700i Li-ion battery charges inside the light through a moisture-protected USB Type-C port, and a side-mounted LED shows the battery's remaining power level. Accommodating tactical grips, the light is fully controlled from dual tail switches—a raised push button for on/off on a momentary or constant-on basis, and a mode switch for selecting high, medium, low, or strobe modes. On any setting or when the light is off, you have instant access to the randomly flashing strobe via the mode switch.

The light's reflector is engineered with crystal coating and precision digital optics technologies for a long throw. The P20iX's strike bezel has high-hardness silicon nitride ceramic tips, which make the bezel more effective in breaking glass or self-defense but less likely to damage the inside of a pocket or pack. Built for durability, the light features an aluminum housing with a Type III hard-anodized black finish, an anti-roll ring, and diamond-pattern knurling for a good grip. Advanced Temperature Control circuitry guards against overheating. O-ring sealed and IP68-rated, the light is submersible to 6.6', and impact-resistant to 6.6 feet.
