Nitecore SRT3 Defender Multi-Color LED Flashlight (Military Gray)
Key Features
  • 0.1 to 550 Lumen Variable Output
  • White and Red/Blue LEDs
  • Emergency Strobe, SOS, Location Beacon
  • Magnetically-Controlled Selector Ring
The military gray 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.

Nitecore SRT3 Overview

The military gray 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
  • Low: 0.1 lumens
  • Turbo: 550 lumens max output
  • One white CREE XM-L2 U2 primary LED
  • One secondary RB LED emitter
  • Deep, smooth aluminum reflector produces smooth beam without holes or hot spots
  • Tight center cone of light with large dimmer peripheral ring
  • Strobe-mode causes temporary blindness and disorientation
  • Two colored secondary outputs:
    • Provides illumination while preserving night-adjusted vision
    • Red provides illumination to read or perform tasks
    • Blue highlights fluids, such as blood, for tracking in low-light
  • Special strobe functions:
    • SOS signal automatically cycles through Morse code sequence
    • Alternating red and blue strobe warning-mode
    • Flashing location beacon
Switching
  • Type: 2-Stage Pushbutton
  • Location: Tailcap
  • Press for momentary activation, click for constant-on
  • Shrouded tailcap helps prevent accidental activation
  • Magnetically-controlled variable output Smart Selector Ring at base of head
  • Non-incremental intensity for precise variable-output selection
  • Incremental function selection
Construction Details
  • Aluminum alloy housing
  • Corrosion and scratch resistant type III hard anodized finish
  • IPX8-rated, submersible to 6.6'
  • Crenellated stainless steel bezel can be used for self-defense or as a window-breaker
  • Double-sided anti-reflective coated and tempered lens
