Surefire E2d "Executive Defender" Flashlight

What do you do when things go bump in the night? If you're prepared for the worst, you reach for the E2d Defender, a personal safety device that packs a powerful defensive punch into a very small package. 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 stainless 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. Batter
