The Defender features:
An advanced technology Xenon lamp that produces a spot-free beam so intense it can momentarily blind an attacker (four times more lighting power than a standard two D-cell flashlight), and its crenellated Strike Bezel allows it to be used as a last-ditch impact weapon. Constructed from aerospace-grade aluminum coated in a super rugged military-specification finish, the pocket-size E2D Defender also features an optically-coated Pyrex lens; high-energy, ten-year shelf-life lithium batteries; a steel pocket clip, and law enforcement-style click-on/off momentary switching for blinding flashes or emergency signaling. A patented lock-out tailcap allows the light to be locked in the off position to eliminate accidental activation when stowed away.
