The black SRT3 Defender Multi-Color LED Flashlight from Nitecore is a powerful and ultra-compact pocket-sized light that is built with military and law-enforcement use in mind. Its primary output comes from a white CREE XM-L2 U2 LED that is infinitely-variable from 0.1 to 550 lumens. A Red/Blue (RB) LED set on the edge of the reflector provides two colored output options for a reduced light signature that preserves night-adjusted vision. Press the 2-stage pushbutton tailcap switch for momentary activation, press and click for constant-on. The output intensity, color outputs, strobe, location beacon, SOS signal, and red/blue strobe, are managed using a magnetically-controlled rotating Smart Selector Ring located at the base of the head.

Built for durability, the light features an aluminum housing with a Type III hard-anodized black finish that resists scratching and corrosion. It is O-ring sealed to be IPX8-rated and submersible to 6.6', and impact-resistant to 5 feet. Its crenellated stainless steel bezel is designed to be used for self-defense, or as a window-breaker. A diamond-textured pattern is machined into the handle to provide a sure grip, especially in cold and wet weather. The included extension tube and the specialized circuitry enable the light to run on multiple battery sizes and chemistries. This versatile light has reverse-polarity protection that prevents damage to the light's circuitry if the batteries are installed incorrectly.
Light Performance
