The SureFire E1B-MV Backup Flashlight (brand part no. E1B-MV) is a compact dual-output light developed originally as a backup for law enforcement professionals, built around SureFire’s MaxVision Beam technology for close-range clarity. SureFire programs the E1B-MV to lead with its full 400-lumen output the moment it’s activated, the way a tactical or self-defense light should, with a secondary 5-lumen setting for tasks that don’t call for full brightness. The MaxVision Beam reflector shapes the output into a smooth, seamless beam that keeps peripheral awareness intact rather than a harsh hot spot, and the body is built from high-strength aerospace aluminum with Mil-Spec anodizing, a stainless pocket clip, and O-ring/gasket sealing for weatherproof reliability. A single 123A battery with a 10-year shelf life powers the light. Among our weapon lights, the E1B-MV suits shooters who want a genuinely compact, high-output backup light for close-range use.
