3000 Lumen Long Throw Tactical Flashlight

The Nitecore SRT7i tactical flashlight offers both power and versatility with its smart selector ring, allowing for precise control. Its high-performance LED can emit up to 3000 lumens and reach a beam throw of over 634 yards. Its heavy-duty springs and 2m impact resistance enable it to withstand harsh environments while still shining brightly. The SRT7i also has tail stand capability, preventing accidental activation and providing a secure attachment point for lanyards. Additionally, the stainless steel bezel with three silicone nitrided inlays can reduce glass to rubble, making it a valuable tool for emergencies. With an IP68 waterproof rating and a covered charging port, the SRT7i is suitable for use in any climate.

Smart Selector Ring

The smart selector ring is located on the tailcap, making it easy to operate with one hand. Simply turn the ring from the locked position to adjust the brightness from 1 lumen up to the maximum of 3000 lumens, and then click over to the tac mode. Along with Nitecore's dual tail switch technology, the controls are straightforward and intuitive, allowing for easy adaptation to your lighting needs.

USB-C Rechargeable with Extended Runtime

The SRT7i comes with a 5000mAh high capacity battery and can be fast charged via its built-in USB-C port. Once it is fully charged, it can achieve a max runtime of over 800 hours on the low mode. When the light is on, a blue power indicator displays the remaining battery power.

5 of 5 SRT7i March 2, 2024
Reviewer: Aaron Kunce from Springfield, OH United States  
Love this flashlight. Always been a fan of the Luminus SFT-70 LED and it’s a great choice for this light as well. The smart ring tail cap works great and step-less brightness adjustment is a feature I love having on a flashlight. As a bonus you have both a lockout mode and a TAC mode, also available via the smart ring selector. It’s a bit on the heavier side, but all in all a great addition to the collection.

5 of 5 Shelf above top shelf is where this light rates! February 29, 2024
Reviewer: Mike H from Corpus Christi, TX United States  
The rotary design is the next level.  Best Flashlight I've owned.  The quality is top notch and the usb-c cover is metal not rubber.  This light is extremely bright on high, almost like a light saber on Star Wars.   We have purchased two of these so far and will be buying another one.  Also, may I suggest: Nitecore Intelligent 21700 Battery System - MPB21 Kit: Lantern, Dual Function Battery Charger.  This gives a back up battery and bonus light/charger kit.  This is another great product that would enhance the purchase of this light.  I have two of them and they are great too.  Thanks Nitecore.
