The Weltool LH2 V2.0 IR Light Head is a specialized, high-performance accessory designed for professional-grade weaponlights, offering infrared illumination for tactical, law enforcement, military, and night operations that rely on night vision equipment. Precision-engineered and compatible with a wide range of existing light bodies, including the Weltool W35 and W65, as well as the Surefire M600DF, the LH2 V2.0 represents a critical enhancement for operators working under low-light and no-light conditions. Compact yet powerful, this single-mode IR light head offers impressive output, rugged construction, and refined compatibility, positioning it as an essential component in the gear setup of professionals who prioritize stealth, performance, and reliability.

At the heart of the LH2 V2.0 is a high-density infrared LED specifically engineered to emit a focused, high-intensity IR beam, making it a perfect match for night vision systems. Unlike visible-spectrum flashlights, infrared emitters are not detectable to the naked eye, making them indispensable for covert operations where visual discretion is critical. The LH2 V2.0 emits a radiant flux of up to 2000mW and boasts a typical radiant intensity of 1150mW/sr, numbers that speak to its capacity for deep, penetrating IR illumination. This allows the user to maintain optimal visibility through night vision goggles or scopes while remaining virtually invisible to threats without NVG capability.

This light head is designed to offer long-distance infrared throw. With a beam distance of up to 597 yards (approximately 546 meters), the LH2 allows users to identify targets, terrain, or structures at a substantial range under night vision, providing a tactical edge in surveillance, reconnaissance, or navigation tasks. The beam profile is optimized for a throwing configuration, ensuring minimal spill and maximum reach. This focused beam is particularly advantageous in outdoor environments, from wide open fields to dense forest settings, where clarity and distance are paramount.

Mechanically, the LH2 V2.0 stands out for its robust construction. CNC-machined from aerospace-grade aluminum alloy, the head is engineered to endure the extreme conditions often encountered in professional operations. Whether mounted on a weapon or handheld flashlight, the structure provides thermal stability, impact resistance, and a secure fit that resists vibration and recoil. The exterior is hard anodized for enhanced abrasion resistance and corrosion protection, and it is available in both classic black and FDE (Flat Dark Earth) finishes. These options allow the operator to tailor the light’s appearance to their gear or camouflage environment, enhancing both form and function.

Another key strength of the LH2 V2.0 is its modularity. It is designed to be seamlessly integrated into Weltool’s modular lighting ecosystem. Compatible with the W35 and W65 weaponlight bodies, as well as flashlight bodies such as the BB3 and BB6, it expands the flexibility of these platforms without the need for additional equipment. Furthermore, its compatibility with the Surefire M600DF body ensures that operators with existing Surefire setups can transition or upgrade to Weltool’s IR capabilities without overhauling their entire lighting system. This cross-compatibility reflects Weltool’s understanding of the real-world operational needs of professionals who often use mixed platforms and demand streamlined integration.

Powering the LH2 is straightforward and efficient. It is designed to run on a single lithium-ion battery, specifically the Weltool UB18-12P 18350 rechargeable cell. When powered by this battery, the light head offers a maximum runtime of up to 70 minutes, a solid duration for mission-based tasks or extended patrols. It’s important to note that the LH2 cannot be powered using dual lithium batteries or dual lithium-ion cells, which ensures safer operation and avoids compatibility errors. This design decision underscores Weltool’s commitment to safe, purpose-built energy delivery, prioritizing thermal regulation and battery longevity without compromising output.

The LH2 V2.0 is a single-mode light head, further emphasizing its mission-focused simplicity. In high-stakes or rapidly evolving tactical situations, the presence of multiple lighting modes can slow down response time or create potential confusion. By focusing on one dedicated high-intensity infrared output mode, Weltool ensures that activation is immediate and consistent every time. There’s no need to cycle through modes or remember sequences—this is a tool meant to do one job, and do it flawlessly.

One of the most important qualities of an IR light head in tactical scenarios is its ability to remain operational under adverse conditions. From temperature extremes to impacts and exposure to water or dust, weapon-mounted lights often endure far more punishment than traditional handheld flashlights. The LH2 V2.0’s rugged build and refined engineering ensure that it continues to deliver peak performance regardless of environmental factors. Its thermal control mechanisms, coupled with the efficient single-mode LED driver, keep output stable and prevent overheating during extended use.

Another subtle but essential feature is the consistent optical clarity offered by the reflector system and lens. Weltool’s design ensures that the infrared beam remains focused and free from distortion, enabling precise illumination even at long distances. This matters in real-life operations where distinguishing friend from foe or identifying a distant object may depend on the integrity of the IR beam pattern.

In terms of installation, the LH2 V2.0 is designed for easy mounting and quick interchangeability. Users can quickly swap this IR head onto compatible light bodies in the field without requiring specialized tools or complex alignment. This modularity reduces downtime and increases readiness, allowing operators to adapt their lighting tools for specific missions on the fly.

The LH2 V2.0 also serves as the standard infrared head on several of Weltool’s flagship weapon lights, including the W35IR and W65IR. These models represent some of the most trusted infrared lighting platforms in the field today, and the LH2’s use in these setups testifies to its reliability, performance, and professional-grade construction.

In conclusion, the Weltool LH2 V2.0 IR Light Head is a finely tuned piece of tactical gear, built to meet the exacting demands of modern law enforcement, military, and security professionals. It offers exceptional performance in a discreet and robust form factor, delivering infrared illumination that integrates effortlessly with night vision devices. Its radiant flux, beam reach, and rugged compatibility make it an ideal addition to any mission-critical loadout. Whether deployed in surveillance, search and rescue, perimeter patrols, or field operations, the LH2 ensures that visibility under the cover of darkness is never compromised.

Its seamless compatibility with multiple flashlight and weaponlight platforms, along with its high output and user-friendly design, makes it a valuable tool for those operating in the invisible spectrum. For those who rely on infrared light to see what others can’t, the LH2 V2.0 is more than just an accessory—it’s a tactical advantage.
