Making use of both a constant-on/constant-off primary button and a momentary-on tail switch—both of which have multiple, user-configurable modes of operation—the ergonomic SureFire Stiletto offers users a great deal of versatility. In its default modes, the flashlight’s brightness can be set to either 650, 250 or 5 lumens via the main button, while the thumb-activated tail button offers only high-intensity output. The knife-shaped light’s MaxVision Beam reflector projects a wide cone of light to illuminate as much of the surroundings as possible, to assist in situational awareness. The 2.8-oz. Stiletto’s integral lithium polymer battery is rechargeable via a Micro USB port (charging cord included) located just below the primary activation button.
