With a rotary control for 10 brightness settings and a powerful 2,000-lumen maximum output, the Nitecore Signature P38 Precise Series Flashlight is a versatile light for professional or enthusiast use. It can run up to 325 hours on low power with a fresh battery.
The tailcap-mounted rotary control has 10 indents for brightness settings ranging from 2 to 2,000 lumens. The wheel is also a push button switch; with the light on, you can press it to enter strobe mode, then rotate to cycle through the slow flash, quick flash, beacon, and SOS modes. With the light in any state, pressing the rotary control for one second activates Strobe Ready, giving instant access to a mode that can disorient and deter an attacker. The rotary control can be used in combination with the tailcap on/off button for direct access to the highest or lowest brightness settings. Battery power indicator lights on the tailcap prevent you from being caught by surprise without a power supply.
The P38 features a type III anodized aluminum housing with a stainless steel bezel ring to reinforce the flashlight's head. The toughened mineral glass lens has anti-reflective coating for optimal light transmission. O-ring sealed for a water-resistance rating of IPX8, the light is submersible to 6.6' and is also impact resistant. Nitecore's Advanced Temperature Regulation technology automatically monitors and adjusts the light's output based on its temperature to prevent damage, while fins built into the P38's housing diffuse operational heat.
