The robust, always accessible 2211X is the lightest weight, most affordable member of SureFire's category-redefining WristLight family. Developed with input from active-duty police officers, this compact, lightweight wrist-worn light boasts a shadow-killing MaxVision Beam at three useful levels: 300, 60, and 15 lumens. When strapped to your support-side wrist, the 2211X is always ready for action. It won't get lost, dropped or left behind when you need it most. Powered by a single disposable 123A battery that can provide up to 13 hours of useful illumination, it makes a great everyday-carry or backup light that's convenient and comfortable to wear 24/7. Always on you and immediately accessible — no matter what.
