Klarus GL3 USB-C Rechargeable Rail-Mounted Light

High-Output Tactical Illumination

The GL3 delivers 2,100 lumens with a 240-meter beam, putting it among the top performers in the rail-mounted category. The focused beam profile prioritizes distance and clarity for threat identification, perimeter checks, and search operations where reach matters.

Quick-Detach Mount System

Tool-free quick-detach mounting allows fast attachment and removal from standard Picatinny rails. Switch the GL3 between platforms in seconds without losing zero on accessories.

Dual-Switch Tactical Operation

  • Tail switch — momentary and constant-on light operation
  • Side switch — mode cycling and lockout
  • Strobe — disorientation and signaling
  • Lockout mode — prevents accidental activation during transport

USB-C Rechargeable Built-In Battery

Charges via USB-C from any standard cable. The integrated battery delivers consistent runtime across all output levels, eliminating the need for disposable CR123A batteries.

Built for Hard Use

Aircraft-grade aluminum body with hard-anodized finish, IPX-rated water resistance, and impact resistance for hard-use environments. The strike bezel adds defensive capability in close-quarters scenarios.

Who the GL3 Is For

The GL3 is built for trained users who want maximum output in a rail-mounted platform with the convenience of USB-C charging and quick-detach mounting — duty professionals, range users, and prepared citizens who value high-performance equipment.
