SureFire X300 Ultra High Output 1000 Lumen Weapon Light - Durable

In this review the SureFire X300 Ultra is examined for serious shooters and professionals who need a reliable, high-output weapon light. The bottom line: this bundle delivers a focused, far-reaching 1000 lumen beam in a virtually indestructible package, and the included extra batteries and Lightjunction cases make it practical for extended operations. For anyone mounting a light to a pistol rail and expecting consistent performance under harsh conditions, the X300 Ultra earns its place as a workhorse rather than a weekend toy.

Key Features

• Mil-Spec body: The hard anodized aluminum construction provides a rugged housing that stands up to demanding field use and rough handling.
• High output LED: The custom LED and TIR lens produce a bright 1000 lumen beam that helps positively identify targets at distance and temporarily disorient threats.
• Precision TIR lens: The lens focuses light into a larger center spot with useful peripheral illumination to maintain situational awareness.
• Ambidextrous switching: The integral momentary- and constant-on switch works for both brief bursts and extended use while remaining accessible from either side.
• Complete battery bundle: Twelve extra CR123A batteries and three Lightjunction cases extend usable runtime so the light can operate for many hours between resupply.
• Secure rail mount: The T-slot thumbscrew clamp fits Universal and Picatinny rails for a firm attachment to most handguns.

Who It's For

The X300 Ultra is aimed at tactical operators, law enforcement, and experienced civilian shooters who need a dependable weapon-mounted light with a powerful, focused beam and durable construction. It is particularly well suited for those who value a single-piece, ambidextrous control and want the convenience of extra batteries stored in Lightjunction cases for patrols or extended range days.

Less appropriate for casual users are those who only need a compact flashlight for pocket carry or non-weapon household tasks, and buyers who require rechargeable battery chemistry or an integrated charger should look elsewhere since this bundle uses disposable CR123A cells.

Pros & Cons
