The Kroma Mil-Spec LED Flashlight from SureFire is a versatile dual-output white LED light with three low-output coloured and an infrared secondary lights. The primary 130-lumen high and 11-lumen low illumination comes from the white LED emitter and SureFire's Total Internal Reflection (TIR) lens. This lens produces a tight centre cone of bright light, with a dimmer wide peripheral ring to help maintain situational awareness.

The TIR lens beam is smooth without holes or hot-spots. Turning the Selector Ring, just behind the head, changes the colour of the low-output from white, to yellow-green, blue, red or infrared.

Each setting has a click-stop function to lock in the output colour. The light's shroudless tactical two-stage tail cap switch features momentary and constant-on modes. Press the pushbutton for low output white, coloured and IR, press further for high output white light. Twist the tail cap for constant-on low output white, coloured and IR. Continue to twist for constant-on high white output.
