2100 Lumen Long Throw Tactical Flashlight

The Nitecore SRT6i tactical flashlight combines performance with Nitecore's Smart Ring selector for ease of use and precise control.The high performance LED produces a 2100 lumens max and reaches over 557 yards of beam throw. The stainless steel bezel with three silicone nitrided inlays reduces glass to rubble, making SRT6i an indispensable tool for emergencies. With an IP68 waterproof rating and a covered charging port, the SRT6i can be used safely in any climate, making SRT6i an amazing tactical package.

USB-C Rechargeable with Extended Runtime

The SRT6i 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 70 hours on the low mode. Combining the heavy duty springs with 2m impact resistance allows the SRT6i to withstand the toughest environments and shine without pause.

Smart Ring Selector

The SRT6i tail cap is designed for the ultimate one handed user experience with the maximum control. The heavy duty primary switch controls momentary and constant activation while the mode pedal has been angled for even easier access while wearing thick gloves. Back in action is the tail stand capability, preventing accidental activation while providing a secure attachment point for lanyards.

5 of 5 New twists on old themes... February 12, 2023
Reviewer: WADE PAGE from Easley, SC United States  
As a seasoned Nitecore flashlight owner and owner of hundreds of others, I do like the Nitecore SRT6i overall. The ring does give the user an easy, quick way to change modes and lockout the light. And the light's beam is very bright with a well defined focal point for an intermediate thrower. But the star of the show for me is the tailswitch. Instead of a somewhat mushy rubber bulb as with most lights, it is a definite, clean click that shuts off on demand when the user lets off. Is it worth the price of admission? In my experience, yes. I'm happy to add the SRT6i to my collection and I would recommend for persons looking for these features all in one light. Delivery was a bit delayed on this one, but it finally arrived and operates better than expected.
