Fenix BC45R Rechargeable Bike Light
The Fenix BC45R bike light will take your night rides to a new level thanks to its uncompromising performance and advanced features. It offers independently controlled wide and long-range beams that can be combined as desired. With a dazzling output of up to 3300 lumens (ANSI) and a beam distance of 286 meters, it turns night into day. The integrated OLED display provides a perfect overview of the currently selected lighting mode and battery status. Power is supplied by a pair of replaceable 18650 Li-ion batteries with a capacity of 3400 mAh, which can be easily recharged directly in the light via a waterproof USB-C connector with fast charging support. The wide floodlight beam smoothly illuminates the entire area in front of the bike, while the long-range spotlight with a modern Luminus SFT-40 LED reliably illuminates even distant obstacles on the road. For maximum comfort, the light is equipped with a wireless remote control, which can be used to operate both spotlights and instantly activate the Turbo mode. The quick-release mount allows tool-free installation on all common handlebars with a diameter of 22 to 32 millimeters. Furthermore, the light can be easily detached from the mount and used as a handheld flashlight. The Fenix BC45R bike light, with its premium construction from aerospace-grade aluminum alloy, is resistant to rain and drops.|
