SureFire's Stiletto is a pocket-sized flashlight packed with features. It utilizes MaxVision Beam technology to produce a powerful 650 lumen beam that can flood a 78 meter area with light. For tasks that don't require a high degree of illumination, the Stiletto can be set to lower output of 250 lumens and 5 lumens. It features a tail mounted tactical switch that will instantly activate the high output mode or a strobe function, and has a front mounted for selecting the other outputs. Instead of the standard, interchangeable batteries, the Stiletto uses an integrated battery rechargeable via micro-USB with a "fuel gauge" to help determine the charging status. The body of the Stiletto is constructed out of durable polymer which is resistant to shock and corrosion, and features a Melonite coated spring steel pocket clip for securing the light firmly in place.
