SureFire X300V-B Infrared and White LED Pistol Weaponlight

Overview of the SureFire X300V-B Weaponlight | X300V-B

The SureFire X300V-B is a dual-output handgun and long gun weaponlight that pairs 350 lumens of white light with a 120 mW infrared (IR) LED. Model X300V-B mounts with a T-slot thumbscrew clamp and runs on two included 123A lithium batteries.

You clear a dark building with night vision, then need full white light the moment you reach a lit hallway. The X300V-B lets you switch between both outputs on the light itself, with no filter to pull off.

Two Lights in One Housing

• White mode: SureFire states 350 lumens, 13,000 candela, and a 228 meter beam.
• IR mode: 120 mW at 860 nm, invisible to the naked eye and built for use with night vision devices.
• Disable mode: a center position on the selector ring prevents discharge during storage and transport.

Who Carries It

Patrol officers, SWAT teams, and military users running night vision get both outputs on one pistol or carbine rail.

Key Features

• Dual output: 350 lumen white LED and 120 mW, 860 nm infrared LED in one body.
• Selector ring: no-look, self-locking ring rotates between white, disable, and IR. No IR filter required.
• Switching: ambidextrous push or toggle tailcap gives momentary-on (press and hold) or constant-on (rotate up or down).
• Runtime: SureFire lists 2.5 hours in white mode and 16.75 hours in IR mode.
• Mounting: T-slot thumbscrew clamp with Universal and Picatinny cross members included.
• Build: aluminum body with a Mil-Spec hard anodized finish (MIL-A-8625 Type III, Class 2).
• Weatherproof: IPX7 rated. SureFire states it survives submersion to 1 meter for 30 minutes.
• Power: two 123A lithium batteries, included. Pair them with SureFire SF123A 123A Lithium Batteries for spares.
• Warranty: backed by the SureFire No-Hassle Guarantee against defects. Batteries and normal switch wear are excluded.

Specifications

Compatibility

• Firearms: fits pistols and long guns with a Picatinny (MIL-STD-1913) or Universal accessory rail. Swap the included cross member to match your rail. SureFire notes some MIL-STD-1913 rails need the Universal cross member.
• Night vision: the IR output is meant for use with night vision devices. It does not show to the naked eye.
• Holsters: choose a holster made for the X300V on your exact pistol model. Do not assume a holster cut for another light will fit.
• Non-railed handguns: need a separate adapter mount, sold separately.
• Need more white light? See the SureFire X300T-B High-Candela WeaponLight. Want white light only? See the SureFire X300U-A Weaponlight.

Intended Users

Law enforcement patrol officers and SWAT operators who work with night vision use the X300V-B to search in IR and switch to white light without a filter. Military units mount it on carbines and duty pistols for low-light missions. Corrections and security teams use the disable position for safe storage between shifts. Civilian shooters and home defenders who own night vision gear choose it for one light that covers both modes.

Available at WCUniforms

WCUniforms is owned by a U.S. Marine veteran and a U.S. Coast Guard veteran who also served as a city police officer and EMT, so we know what a duty light has to survive. Since 2013, our San Diego team has supplied officers, soldiers, and armed civilians, and this SureFire ships from our Michigan warehouse to customers across the United States. Compared with a white-light-only pistol light, the X300V-B gives night vision users a second mode without adding a second light.
