SureFire M640V-Pro Vampire (M640V-TN-PRO) Review: Dual‑Spectrum Power in a Low‑Profile, Duty‑Ready Package

If you run night vision or split time between white light and IR work, the SureFire M640V‑Pro Vampire in Tan (FDE) is one of the few lights that truly bridges both worlds without compromise. We mounted the M640V‑Pro on a 12.5-inch carbine and a 16-inch patrol rifle, ran it through live‑fire drills, and spent a night session under NODs to see how it handled real‑world use. The verdict: its dual-spectrum head, robust “Pro” low‑profile mount, and SureFire’s trademark reliability make this a serious option for professional duty and discerning enthusiasts.

Why this Scout Light Pro stands out in hands‑on use

The M640V‑Pro Vampire combines a 350‑lumen white light for PID with a 120 mW IR illuminator for night‑vision work, selectable by a simple twist of the bezel. In practice, that means no swapping heads or carrying two lights. The “Pro” low‑profile mount lets you hug the rail tightly and choose either the included Picatinny or M‑LOK plate, so cable routing stays clean and you save precious rail space for other mission‑critical accessories.

Key features we verified during testing

• Dual-spectrum head: 350 lumens white light and 120 mW IR output, switched by rotating the bezel—positive detents you can feel even with gloves.
• Low-Profile Mount (LPM): The Scout Light Pro swing‑arm puts the body closer to the rail for better ergonomics and reduced snag potential.
• Two mounting plates in the box: Picatinny (1913) and M‑LOK, plus hardware—no extra shopping to get it on your rifle.
• SureFire TIR lens: Focused hotspot with useful spill for situational awareness; under NODs, IR provides a clean beam that avoids overwhelming your tubes at closer ranges.
• Rugged build: Hard‑anodized aluminum body, O‑ring sealed, and designed to shrug off recoil and the elements.
• Tailcap activation: Reliable clicky tailcap out of the box; compatible with SureFire remote switches if you prefer tape‑switch control.
• Neutral signature: In IR mode, there’s minimal visible signature to the naked eye while still giving your NODs a strong, usable illuminator.

Real-world benefits you’ll notice immediately

• Fast mode changes: White-to-IR switching is tool‑free and intuitive—ideal when transitioning from exterior white‑light search to IR‑only movement.
• Better rail ergonomics: The Pro mount tucks the light in tight, opening up hand placement options and keeping cables out of the way.
• Confident PID and navigation: White light offers a crisp hotspot for identification; IR cast is clean and controlled for effective target illumination under NODs.
• Duty-grade confidence: Zero drama through recoil and weather—ours stayed locked up with no flicker or shift.

Our test notes (the stuff you only learn by using it)

• Beam quality: The white beam isn’t a wall of lumens, but it’s purposefully balanced—tight core for distance with enough spill to check corners. The IR beam offers a similarly disciplined pattern that plays nicely with Gen 3 tubes.
• Controls: The bezel detents for white/IR are tactile and easy to confirm by feel in the dark. The tailcap has a predictable press for momentary or click for constant.
• Mounting: The included Picatinny and M‑LOK plates are a real win. We ran M‑LOK on a free‑float handguard and Pic on a duty upper—no adapters needed.
• Cable management: With the light sitting closer to the rail, we found it easier to route a remote lead without snags. If you stay with the tailcap only, it’s even simpler.

What’s in the box

• SureFire M640V‑Pro Vampire Scout Light (Tan/FDE)
• Low‑Profile Mount (swing‑arm) with Picatinny and M‑LOK plates + mounting hardware
• User documentation
• Note: Remote/tape switch is optional and sold separately.

Who should choose the M640V‑Pro Vampire

• Night‑vision users who want a single unit to handle both white and IR illumination.
• Duty, defense, or training setups where rail space, robustness, and repeatable activation matter.
• Hunters and rural users who often switch between visible and IR in the same outing.

Potential trade‑offs to consider

• Output philosophy: 350 lumens is purpose‑driven, not a lumen race. If you want maximum white‑light brightness only, a dedicated high‑lumen model may suit you better.
• Accessories: Remote switch not included. Many will want to add a SureFire tape switch for optimized ergonomics.
• Price: Premium build and dual‑spectrum capability come at a premium price—but it’s proven, duty‑grade gear.

Installation tips for a cleaner setup

• Pick your plate first: Choose M‑LOK or Picatinny based on your handguard, then set the swing‑arm angle to tuck the light close without shadowing your front sight or PEQ.
• Dry‑fit your cables: If you add a remote, mock up the routing before tightening clamps to keep the cable off hot gas blocks and out of grip zones.
• Confirm mode by feel: Practice the bezel rotate for white/IR with eyes closed or under NODs—those muscle‑memory reps pay off.

Frequently asked questions

How do I switch between white and IR?

Rotate the bezel until it clicks into the desired mode. The detents make it easy to confirm by feel, even with gloves or under NODs.

What batteries does it use?

The Vampire series uses CR123A lithium batteries. Check your packaging for exact battery count included and keep quality spares on hand.

Is a remote/tape switch included?

Not typically. The light ships with a tailcap push‑button and works great as‑is, but it’s compatible with SureFire remote switches if you prefer.

Will it hold up to recoil and weather?

In our testing it ran flawlessly on 5.56 and .308 platforms across hot and wet conditions. The anodized aluminum body and sealed construction are built for duty use.

Bottom line: A mission‑flexible white + IR solution you can trust

The SureFire M640V‑Pro Vampire delivers dependable, switch‑on performance in both visible and IR spectrums with a mount that actually makes your rifle feel better to run. If you need one light to cover both daytime PID and night‑vision illumination—without compromising durability or ergonomics—this is the one we’d buy again.
