Purposefully crafted to offer brighter and more consistent light, the Bushnell RUBICON flashlights pair top-quality Cree LEDs with proven optics technology developed during Bushnell"s 65-year history. The innovative Total Internal Reflective (TIR) optic collimates light for better visibility, while the Cree LEDs provide bright, consistent illumination throughout the beam. With utility and affordability at the forefront of design, Bushnell has combined energy-efficient Cree LEDs with a regulated circuit to deliver consistent brightness throughout the battery lifecycle. In addition, each RUBICON flashlight is powered by AA batteries, resulting in a lower total cost of ownership than the CR123-powered lights on the market. Each RUBICON flashlight is equipped with a standard light setting and a special Red Halo low-lumen mode designed to enhance sight without compromising natural night vision. Adventure ready, RUBICON flashlights are constructed with durable aircraft-grade aluminum. Certified by the American National Standards Institute (ANSI), each light has been tested for light output, beam distance, impact resistance (at one meter), protection against water penetration and run time.
