Packing an impressive output of 2000 lumens in two high-power LEDs, the RN 2000 Bike Light is a brilliant all-rounder that will take you from busy streets to challenging trails. The RN 2000 stands out for its double lens system with two different beam options. The floodlight beam gives a broad and uniform carpet of light that extends along the way, and the combined floodlight and spotlight beam ensure coverage and distance, enough for dark paths, trails, or fast rides. In addition, this bike headlight features a built-in light sensor that automatically switches to a brighter setting when entering a tunnel and a vibration sensor to conserve power in a pit stop. Controlling this bicycle light is dead simple with the remote control, which extends the on/off and mode switch functions to the handlebar, so you can focus solely on the road ahead. Moreover, you can instantly skip to a full output mode at the press of a button, thus navigating dark roads with total confidence. The up-down button on the light unit also makes it a breeze to get the correct illumination. Powered by two integrated batteries, this bike front light provides a max runtime of 17.5 hours. The integrated USB-C charging and discharging port allows you to recharge the battery or power your bike computer, smartphone, or other devices while on the go. Plus, the RN 2000 utilizes a robust aluminum body incorporating internal thermal management to get rid of excess heat and maximize light output efficiency. With an IPX6 waterproof rating, the RN 2000 light is reliable enough to penetrate even heavy rain to illuminate your way. When it comes to mounting, the GM quarter-turn mounting system can fix the light quickly and securely to most handlebars. Dual LED setup, double optics, wireless remote control, smart sensors, USB-C fast charging and discharging...this powerful RN 2000 propels you over every ride.
