Upgraded to Nitecore NL2153HPi 21700 5,300 mAh lithium battery
Authorized Nitecore Dealer Exclusive.
As a new breakthrough in the Smart Ring Tactical Series, the NITECORE SRT7i is equipped with the 4th generation Smart Selector Ring, available with rotation & press for one-handed control of modes switching and stepless brightness adjustment, ideal for instant response in tactical applications.
Featuring stepless brightness adjustment from 0 – 3,000 lumens, the SRT7i can provide a professional and precise way of controlling the brightness in various tasks. It is equipped with dual 2-stage buttons on the tail. Half press and hold the MODE Button to access TURBO and full press the MODE Button to access the STROBE.
Utilizing a Luminus SFT-70 LED, the SRT7i has a max output of 3,000 lumens, about 200% higher than the previous generation. With a peak beam intensity of 87,500cd, it can provide a max throw of 580 meters, suitable for night searching and more.
The included NITECORE 21700i Li-ion battery included (NL2150HPi 5,000mAh) features dual way output with positive and negative polarities at both ends and enables 800 hours max runtime on 0.1 lumens ULTRALOW Level with a highly efficient output of 15A. It is USB-C rechargeable, available with a reversible plug-in. Besides, it only takes 2.5 hours to fully charge the SRT7i.
The strike bezel of the SRT7i is designed with high hardness silicon nitride ceramics, which enables a quick and easy operation for self defense and glass breaking. The tactical U-shaped tail cap is compatible with a lanyard, available with accidental activation prevention and tail stand capability. The SRT7i is constructed from aero grade aluminum alloy with HA III military grade hard-anodized finish. It is all-weather applicable, IP68 rated (2m submersible and waterproof), and 2m impact resistant. It is equipped with an anti-impact reverse polarity protection mechanism, specially designed for shooting sports.
