The Nitecore P10i is a high-performance tactical flashlight engineered for professionals who demand reliability, power, and compact design. With a maximum output of 1800 lumens, it utilizes a Luminus SST-40-W LED to deliver a piercing beam that reaches up to 317 yards (290 meters)—ideal for law enforcement, military, and emergency responders who need dependable illumination in high-stakes environments.
Built from aerospace-grade aluminum alloy and finished with a HA III military-grade hard anodization, the P10i is both lightweight and rugged. It weighs just 2.96 ounces and measures 5.79 inches in length, making it easy to carry on a duty belt or in a pocket. The flashlight is IP68-rated, meaning it’s fully waterproof and dustproof, with an impact resistance of 1 meter, ready for harsh weather and rough handling. Powering the P10i is a proprietary 21700i Li-ion battery (4000mAh), which supports USB-C fast charging directly through the flashlight's protected port. This battery system ensures high efficiency and extended runtimes up to 90 minutes on high and 38 hours on low. The flashlight also features a battery level indicator and supports backup power via two CR123 or RCR123 batteries, utilizing the included adapter.
The user interface is designed for tactical efficiency. It features dual tail switches: a raised power button for momentary or constant-on activation, and a flat mode button for cycling through three brightness levels (Low, Medium, High) and accessing the strobe ready mode. The strobe function uses non-linear flashing patterns to disorient threats more effectively than traditional strobes—an essential tool in self-defense or tactical scenarios. The P10i’s beam is optimized using Precision Digital Optics Technology and a crystal-coated reflector, producing a focused hotspot with ample spill for situational awareness. The ceramic-tipped strike bezel adds a layer of utility for emergency glass breaking or close-quarters defense.
