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.

Brightness Levels:
Turbo (3): 2100 lumens - 30 mins runtime
Mid (2): 300 lumens - 7 hrs 30 mins runtime
Low (1): 30 lumens - 70 hrs runtime

Plus Strobe (2100 lumens)

Advanced temperature regulation (ATR) regulates the output of the SRT6i according to the working and ambient temperature to maintain optimal performance while preventing the LED from overheating. The outputs are measured in total of runtime, including output at reduced levels due to temperature or protection mechanisms in the design, causing the brightness level to drop down.

Maximum beam distance 510 meters, waterproof to IP68 and resistant to impacts up to 2 meters.

Includes: Nitecore NL2150HPi 5000mAh 21700 battery, spare o-ring, pocket clip, CR123 battery magazine, USB-C charging cable, holster, lanyard.
