SureFire M640V Scout Light Pro Infrared w/ Z68 Tailcap

Command the night with long-range multi-spectrum illumination using the SureFire M640V Scout Light Pro Infrared (Vampire) Weaponlight in Black. Engineered as the full-size dual-output benchmark for modern tactical carbines, designated marksman platforms, and patrol rifles, the M640V provides seamless transition between high-intensity visible white light and covert infrared (IR) illumination. Powered by a two-cell 6-volt battery system, this battle-tested weaponlight produces 350 lumens of brilliant white light or 120 mW of invisible 860 nm IR illumination—delivering crisp positive target identification (PID) at extended distances while completely eliminating the need for add-on IR filters, spare heads, or redundant illumination devices.

Optical performance is driven by SureFire’s proprietary Total Internal Reflection (TIR) lens system, which shapes the regulated LED output into a focused 13,000-candela beam reaching out to 228 meters. This hybrid beam profile punches through photonic barriers and obscurants with a concentrated center hotspot, while casting ample peripheral spill to maintain situational awareness in dynamic environments. Switching between spectrums is instantaneous and foolproof: simply push and twist the knurled front selector bezel to select between white light, a tactile system lockout/disable setting, or infrared illumination optimized for night-vision goggles (NVGs). Driven by two included CR123A lithium batteries, the M640V yields 2.5 hours of continuous white light or an impressive 16.75 hours of dedicated infrared runtime.

To eliminate bulk and optimize weapon integration, the M640V features SureFire’s Low-Profile Mount (LPM). This versatile pivoting mount allows operators to tuck the light chassis tightly against top rails, laser aiming modules (such as NGAL, PEQ-15, or MAWL devices), and backup iron sights to dramatically streamline the host rifle's profile. The package ships complete with interchangeable mounting cleats for both MIL-STD-1913 Picatinny rails and M-LOK slots. Machined from high-strength aerospace aluminum, O-ring sealed to IPX7 waterproof standards, and cloaked in an abrasion-resistant Mil-Spec Type III hard-anodized black finish, the M640V Vampire delivers mission-critical multi-spectrum dominance in a lightweight 4.15-ounce footprint.

Features

Dual-Spectrum V-Series Bezel (White & IR):
Allows rapid on-the-fly selection between 350 lumens of visible white light, an off/disable lockout mode, and 120 mW of 860 nm infrared illumination by rotating the self-locking selector bezel.

SureFire Low-Profile Mount (LPM) System:
Features an innovative pivoting chassis that allows the light body to rotate tightly against the rail, maximizing clearance around top-mounted IR lasers, foregrips, and optics while eliminating snag hazards.

High-Intensity 13,000-Candela TIR Optics:
Precision Total Internal Reflection lens focuses output into a tight 228-meter center beam for medium- to long-range target discrimination, surrounded by generous peripheral flood for room clearing.

Extended Dual-Cell (6V) Runtime:
Powered by two included 123A lithium batteries, delivering a steady 2.5 hours of continuous white-light output or up to 16.75 hours of dedicated infrared night-vision illumination.

Turnkey Dual Mounting Cleats (M-LOK & 1913 Picatinny):
Ships standard with factory hardware for direct attachment to M-LOK handguard slots as well as MIL-STD-1913 Picatinny rail sections.

Shrouded Z68 Pushbutton Tailcap Switch:
Factory-equipped with SureFire's reliable Z68 click-tailcap switch, offering intuitive partial-press momentary activation, full-click constant-on functionality, and a protective raised shroud against accidental discharge.

Severe-Duty IPX7 Waterproof Construction:
Precision CNC-machined from aerospace aluminum with a tempered optical glass window and O-ring sealing, providing submersible waterproof integrity down to 1 meter for 30 minutes.
