One of the brightest lights of its size on the market today, the Jetbeam SF-R28 Rechargeable LED Flashlight is a potent combination of power and functionality. Less than 6 inches long and powered by just a single 18650 battery, this potent torch can produce a scorching 1500 Lumens of illumination that can throw nearly 800 feet away, thoroughly outshining its competitors (literally). The light also comes with a trio of dimmer outputs, ranging from 400 Lumens down to 10 Lumens, for when such intense illumination isnt required, as well as a special Strobe Function that can be used to disorient an attacker. The SF-R28 features a special machined aluminum reflector and a double-coated mineral glass lens that combine to provide a far-throwing, evenly-dispersed beam great for all situations. The SF-R28 is designed to not only be durable and long-lasting, but to also be as convenient and straightforward to use as possible. Constructed using aero-grade aluminum alloy and coated with a hard-anodized finish, this rugged light is resistant to scratches, moderate impacts, and even powerful jets of water. The user-friendly light even features a special micro-USB charging port where its 18650-power source can be recharged internally, saving you time and leaving no need for a separate charger. Intelligent in its design and potent in its output, the Jetbeam SF-R28 Rechargeable LED Flashlight is a great illuminator for just about any user.
