Overview

Built for a fixed-mount long gun setup, this light is intended for hunters and shooters who want simple, controlled illumination on a Picatinny rail. It delivers 625 lumens on high, with a lower 60-lumen setting and a strobe option available through the TEN-TAP programmable switch. The included push-button tail switch and remote pressure switch support one-handed operation, while the shock-mounted aluminum housing and impact-resistant BOROFLOAT glass lens add durability to the package. Powered by two included CR123A batteries, it offers a compact 5-inch profile for rifles or shotguns where a dedicated light is preferred.

Pros

  • 625-lumen output provides strong illumination for dedicated long-gun use.
  • TIR optic delivers a concentrated beam with peripheral illumination.
  • Shock-mounted construction and impact-resistant BOROFLOAT glass lens add durability.
  • TEN-TAP programming offers high/strobe, high only, or low/high options.
  • Includes both push-button tail switch and remote pressure switch for flexible operation.
  • Picatinny rail grabber with thumbscrew allows straightforward fixed-mount attachment.

Considerations & Trade-offs

  • Fixed-mount design means it is intended for Picatinny rail use, so it is not a universal fit for every long gun setup.
  • The included remote pressure switch adds control options, but it also introduces more setup and cable management than a simple tail-switch-only light.
  • At 625 lumens on high, it offers a focused long-gun light package, but users who want a simpler or lower-output setup may find the feature set more than they need.
  • It runs on two CR123A lithium batteries, so ongoing use depends on keeping those batteries on hand.
