If you're in law enforcement or need a serious long-distance flashlight, the SRT6i is what you've been waiting for.

Nitecore has been outfitting professionals for years, and their gear is trusted by over 15 international agencies. They know what works in the field—whether it's handling emergencies or navigating tough environments.

This new model blends the best of Nitecore's floodlights and long beam features into one powerful package. Think of the robust features from their SRT7GT and P20ix, but even better.

The twist ring and two-stage tailcap switch let you control the light exactly how you need it, from bright, distant signaling to more subdued settings for everyday tasks.

What's really cool about this model is the two-stage mode button—it offers instant access to turbo or strobe modes, even when the light is off. This kind of quick flexibility wasn’t available on their older models.

Plus, it comes with strong strike bezels for breaking glass, removable batteries, and quick USB-C charging—everything you'd expect from a brand with Nitecore's experience.

Looking for a top-notch flashlight upgrade this year? Don't overlook the SRT6i. It’s packed with features that make it stand out in any toolkit.
