KLARUS FlatTac X1 Tactical EDC Flashlight | 4200 Lumens & Self-Defense Features

Klarus FlatTac X1 Tactical EDC Flashlight (X1E / X1K)

The Klarus FlatTac X1 is a serious tactical flashlight built for law enforcement, military, and security use. The perfect everyday carry (EDC) flashlight. It delivers up to 4200 lumens with a fast, instinctive dual-switch tailcap so you can activate and change modes without hunting for controls. The OLED display provides real-time battery and mode status, so you always know what output you’re running before you step into a dark area.

Choose the model that matches your carry and control needs: X1E is the streamlined duty configuration for speed, grip, and low-profile carry. X1K adds an integrated knuckle ring plus a ceramic bead for enhanced retention and glass-breaking / emergency entry capability. Both models have 4 glass breaking ceramic beads on the head of the flashlight.

Quick Highlights

• Up to 4200 lumens (high-intensity tactical output)
• Five modes: Turbo, High, Moonlight, Strobe, SOS
• Tactical strobe for disorientation, signaling, and high-stress situations
• OLED display shows battery, brightness, and active mode
• USB-C fast charging + up to 48-hour runtime on low

Control Built for Pressure

The FlatTac X1 uses a tactical tailcap dual-switch designed for fast, blind operation. That matters on patrol, during building checks, and in any scenario where you need immediate light without taking your eyes off the environment. Switch between Turbo for maximum visibility, High for sustained output, and Moonlight for close-range tasks without blowing out your night vision.

Tactical Strobe + SOS When Light Isn’t Enough

The dedicated strobe is built for situations where you need attention, signaling, or a quick tactical advantage. SOS is included for emergencies and field use when you need a clear visual signal.

Duty-Ready Build + Carry

With a slim, flat profile, the FlatTac X1 carries comfortably in a pocket, kit, or duty setup while still providing a stable, confident grip. It’s rated IPX6 weatherproof to handle wet conditions and hard use, and the USB-C charging system keeps downtime minimal.

X1K Variant: Knuckle Ring + Ceramic Bead

If you want added control in close quarters, the X1K version includes a built-in knuckle ring and ceramic bead for stronger retention and glass-breaking capability in emergency entry or rescue scenarios.
