SureFire is a California-based manufacturer of flashlights and the undisputed leader in military and law enforcement tactical gear. The robust, extremely powerful lamps have been used by numerous emergency services around the world for more than three decades and impress with their uncompromising quality and reliability. The flashlights, which are primarily intended for professional use by the police, military and special units, usually consist of a CNC-machined aluminum housing with an anodised surface, while the lenses are made of high-temperature-resistant Pyrex glass. The extremely narrow manufacturing tolerances make a significant contribution to the high luminous efficacy of the lamps.
