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 Works great August 16, 2023
Reviewer: Ronald Hopkey from Geneseo, IL United States  
I use this flashlight for work and it does a great job lighting up dark ceilings and spaces, my only complaint is with the holster I've only had the light a couple of weeks and it has come apart where it attaches to my belt making it useless.

5 of 5 SRT7i July 17, 2023
Reviewer: David Falgout from Rayne, LA United States  
I own many lights from Nitecore.  I like them all. However the SRT7i is so handy, variable light out put etc.  Beam is very powerful and useful. I have only had it for 2 weeks. Time is the true test!  I could see myself buying a second one. BTW blows away all "olight" offers!

5 of 5 Great all-around flashlight June 12, 2023
Reviewer: Anonymous Person from Vacaville, CA United States  
The Nitecore SRT7i flashlight is a high-powered light that has one feature I think is great: it is fully adjustable from 0 to 3,000 lumens, rather than a stepped, sequential switch like most flashlights! Powered by a 5,000 mah 21700 battery, it also provides light for an extended period. My only complaint is that, like most flashlights currently available, it is a smaller diameter light that does not "fill my hand" like my old favorite Nitecore EA81.
