The Millennium M511B WeaponLight replaces the weapon's original handguards and features built-in switching without any exposed wiring. Because of its lightweight and integrated design, this model is most recommended for law enforcement applications and civilian home defense. Each unit is equipped with four separate switches: (1) A pressure sensitive momentary activation pad (2) a constant-on switch, and (3) a system disable switch to lock the light in the OFF position for covert operations or to eliminate accidental light activation during storage. The M511B is powered by six lithium batteries and produces 250 lumens for one hour of runtime with the high-output lamp, or 500 lumens for 20 minutes with the included ultra-high output lamp.

  • Batteries - Six SureFire lithium SF123 3.0 Volt with 10-year shelf life
  • Lamp Assembly/Runtime - SureFire MN20 xenon/halogen gas-filled lamp assembly with 250 lumens output for 60 minutes, or 500 lumens for 20 minutes with included MN21 ultra-high output lamp assembly
  • Construction - Nitrolon (non-conductive, impact-resistant, aramid glass-filled polymer) housing, Pyrex lens window, shock-isolated aluminum bezel with hard-anodized finish
  • Switching - Pressure sensitive momentary activation pad, constant-on rocker switch, system disable rotary switch
  • 2.5" beam-focusing TurboHead reflector for longer range
  • Flawless white beam, always in focus
  • Bright enough to temporarily blind an opponent
