The NITECORE P20UV v2 has been refined based on 1000s of user comments to provide you with the best tactical experience possible. This flashlight throws 1000 lumens over 179 yards, boasting 2.5 hours of run time on high and up to 46 hours on low. The dual-switch tailcap makes for easy one-handed operation with direct access to turbo and strobe. At under 6 inches and just 4.71 oz, an IP68 rating, and 1 meter of impact resistance; the new P20UV v2 is ready for duty. The P20UV v2 operates on a single 18650 battery or 2x CR123A batteries, increasing its versatility. Multi power options, combined with a power indicator in the tail cap, means a dead battery will never surprise you again. The bezel features three silicon nitride ceramic inlays for enhanced glass breaking. Aero-grade aluminum with diamond knurling in key locations enhances grip and durability. Designed for military, police and security personnel, the P20UV v2 always allows direct access to turbo and strobe mode. The light can be customized with three operating modes: tactical mode, law enforcement mode, and daily mode for different usage scenarios.
