The Nitecore SRT6i flashlight has a maximum output of 2100 lumens from the high performance LEDs and is powered by an iSeries 21700 li-ion battery (Nitecore NL2150HPi included). The battery is rechargeable inside the torch via a USB-C port with a rubber cover for resistance to dust, water and impact.

The latest addition to Nitecore's SmartRing Tactical (SRT) series, the SRT6i has a rotating ring towards the tail end of the light which allows for smooth and simple output selection. On the tail cap are two switches: the power button which turns the light on and off and provides momentary illumination and the 2-stage mode button activates the randomly changing strobe mode.

In addition to the dedicated tactical mode for direct momentary activation of low and turbo mode, the SRT6i has a strong strike bezel for emergency use, a tactical U-shaped tail cap and is compatible with a range of optional accessories, including 40mm filters and traffic wands, gun mounts and the Nitecore RSW2i remote switch.
