The Tactical Advisor found a fake Surefire weaponlight for airsoft use on Amazon so he purchased it to compare it to the real deal. The its maker says the replica tactical weapons light boasts a powerful white light with a brightness of 400 lumens. Powered by two CR123A batteries (not included), which are inserted from the head of the flashlight to prevent accidental detachment.  The light offers two activation options: a momentary-on pressure switch located on the tail cap for quick bursts of light, and a constant-on button switch for sustained illumination.  The included 20mm picatinny rail mount allows for easy attachment to rifles for tactical applications or home defense. Crafted from strong, aircraft-grade aluminum with a black matte finish.
