Become The Fear Of The Unknown. Keep your whereabouts in the dark with the X400VH, which integrates with SureFire's revolutionary MasterFire Rapid Deploy Holster for quick deployment and instant-on light activation, an ideal combination in a low-light, high-stress situation. Even better, the X400VH features our innovative V-Series head, which provides both white-light and infrared illumination, plus an integral Class 1 infrared laser aiming device. Choose between 350 lumens of visible, tactical-level light or twist the bezels self-locking selector to switch to generate 120 mW of IR illumination for use with NVGs. The infrared laser provides a highly visible dot for aiming during stealth operations where focusing on iron sights with NVGs can be challenging. When it comes to sheer mission/weapon compatibility the X400V dominates in the dark.
