Mastering Low-Light Readiness: The SureFire X400UH-A-GN Weapon Light with Green Laser

For anyone serious about tactical readiness, personal defense, or professional duty, reliable illumination and precision aiming are paramount, especially in low-light conditions. The SureFire X400UH-A-GN Weapon Light with Green Laser represents the pinnacle of weapon-mounted technology, engineered to provide unparalleled performance when every second and every shot counts. This advanced accessory isn't just a light; it's an integrated system designed to dramatically enhance your situational awareness, target identification, and accuracy in challenging environments.

Are you searching for the ideal weapon light that offers a potent combination of brightness and a highly visible laser? Do you need a robust, recoil-proof solution that integrates seamlessly with a rapid-deploy holster system? The SureFire X400UH-A-GN is specifically crafted to meet these critical demands, serving as an indispensable tool for law enforcement officers, military personnel, competitive shooters, and armed citizens who prioritize top-tier performance from their gear.

Unrivaled Illumination: A Beacon in the Darkness

At the core of the X400UH-A-GN's impressive capabilities is its powerful 1000-lumen white LED light output. Lumens directly translate to the sheer amount of light projected, and 1000 lumens is a significant output, capable of overwhelmingly bright illumination. This intense beam is focused by SureFire's proprietary Total Internal Reflection (TIR) lens, which optimizes the light delivery to create a smooth, far-reaching beam with a large, bright central spot. This design ensures that you not only brightly illuminate your target but also maintain excellent peripheral vision, crucial for assessing threats and identifying potential dangers in dynamic scenarios.

• Superior Target Identification: The 1000-lumen output provides the necessary power to pierce through shadows, fog, or even smoke, allowing for positive target identification at considerable distances. This is vital in self-defense situations where distinguishing between a threat and a non-threat is a matter of life and death.
• Disorienting Capability: The sheer intensity of the light can temporarily disorient an assailant, buying valuable seconds for tactical response or escape.
• Enhanced Situational Awareness: The broad, uniform beam produced by the TIR lens illuminates a wider area, providing a comprehensive view of your surroundings, which is critical for maintaining tactical advantage.

The LED is recoil-proof, meaning it is designed to withstand the harsh vibrations and concussive forces generated by repeated firearm discharge without flickering, dimming, or failing. This unwavering reliability is a hallmark of SureFire products, ensuring that your light will perform consistently when you need it most.

Precision Aiming with a Highly Visible Green Laser

Complementing the powerful white light is an integrated 5mW/515nm green laser sight. Why a green laser? Green lasers, operating at a wavelength of 515 nanometers (nm), are significantly more visible to the human eye, particularly in daylight and transitional lighting conditions, compared to traditional red lasers. This superior visibility ensures rapid target acquisition and precise aim, even against complex backgrounds or in bright environments where a red laser might wash out.

• Instant Target Acquisition: The highly visible green dot allows for extremely fast aiming, reducing the time it takes to get on target. This is particularly beneficial in high-stress situations or when engaging multiple targets.
• Enhanced Accuracy: By providing a clear point of aim, the laser helps shooters achieve greater precision, especially for difficult shots or when shooting from unconventional positions.
• Training Aid: For training purposes, the laser provides immediate feedback on trigger control and aiming errors, helping shooters improve their technique without firing a round.
• Minimal Re-zeroing: SureFire's robust construction and precise engineering mean the laser sight rarely requires re-zeroing once it's sighted in, maintaining its accuracy shot after shot.

The integration of both white light and a green laser provides unmatched versatility. Users can select light only, laser only, or a combination of both, adapting to the specific demands of any given scenario with the ambidextrous toggle switch. This flexibility ensures you always have the right tool for the job.

Seamless Integration with the SureFire Masterfire Rapid Deploy Holster

One of the most innovative features of the X400UH-A-GN is its designed compatibility with SureFire's revolutionary Masterfire Rapid Deploy Holster. This partnership dramatically enhances weapon deployment and activation speed. The unique bezel with cam slots and pin slots on the light's body are specifically engineered to lock the X400UH-A-GN, and by extension, the attached weapon, into the Masterfire holster.

• Optimized Draw Angle: The system secures the weapon at an advantageous angle for quick, smooth, and consistent deployment.
• Automatic Activation: When the weapon is drawn from the Masterfire holster, the X400UH-A-GN is designed to automatically activate the light and/or laser, eliminating the need for a separate activation step. This saves critical milliseconds in a high-stakes encounter.
• Secure Retention: The interlocking design provides secure retention of the weapon within the holster, preventing accidental dislodgement while ensuring immediate access when needed.

This integration transforms the X400UH-A-GN from a simple accessory into a foundational component of a rapid-response system, offering a significant tactical advantage in scenarios demanding immediate action.

Built for the Toughest Conditions: Durability and Reliability

Constructed from high-strength aerospace aluminum with a Mil-Spec hard anodized black finish, the SureFire X400UH-A-GN is built to withstand the rigors of real-world use. This material choice ensures exceptional durability and resistance to corrosion, abrasion, and impact.

• Battle-Proven Construction: The aluminum body is lightweight yet incredibly robust, capable of enduring the harsh environments encountered in duty, training, and self-defense situations.
• Waterproof Design: The unit is waterproof, ensuring reliable operation even when exposed to heavy rain, splashes, or accidental submersion. This feature is crucial for maintaining functionality in diverse weather conditions or tactical environments.
• Compact and Lightweight: Despite its powerful output and robust construction, the X400UH-A-GN maintains a compact profile (3.70" OAL) and a light weight (4.90 oz), minimizing bulk and ensuring it doesn't interfere with weapon handling or balance.

The X400UH-A-GN utilizes readily available CR123A batteries, providing a run time of 1+ hours, ensuring sufficient operational duration for most engagements and training sessions. The package includes batteries, allowing for immediate use right out of the box.

Universal Compatibility and Ambidextrous Control

Designed for versatility, the SureFire X400UH-A-GN mounts securely to most Universal and Picatinny (MIL-STD-1913) rails, making it compatible with a wide range of rail-equipped handguns. Its ambidextrous toggle switch ensures that both right-handed and left-handed shooters can easily activate the light and laser, providing intuitive control regardless of the shooting hand. This design consideration ensures that the light can be deployed effectively by a broad user base.

Whether you're looking to upgrade your personal defense handgun, equip your duty weapon, or enhance your competitive shooting setup, the X400UH-A-GN offers a professional-grade solution. Its robust design, powerful output, precise aiming capabilities, and seamless Masterfire holster integration make it a top choice for those who demand the absolute best from their gear.
