【2024 Optimized Version: High Brightness & 190° Wide Angle & Long-Distance Illumination & Light Sensor Auto-On Mode】Adopting a single high-density LED, this light achieves clear, bright, uniform, and soft illumination. With a maximum output of 1000 lumens, it can illuminate up to approximately 300 meters (high beam) ahead. The 190° wide-angle illumination covers a wider area than usual, like a light breaking through the darkness on any black night, allowing you to visually confirm the road width and surface conditions at night. It serves as a night light for riding in the dark, enhancing visibility during nighttime cycling and alerting surrounding drivers and pedestrians to the presence of the bicycle. Equipped with a light sensor, long-pressing the power button activates the auto-on mode, which automatically turns the light on and off by sensing the brightness of the environment, making it very convenient for commuting. 【2024 Optimized LCD Screen Digital Remaining Power Display & Type-C USB Rechargeable Light & Large Capacity Built-in】This bicycle light is equipped with a charging level display screen that shows the remaining battery life, unlike the usual remaining power indicator lamps or percentage displays, it shows the remaining usage time. The available usage time varies depending on the mode, so you can see at a glance how much time is left. You don't have to worry about the battery running out suddenly while riding, and it's easier to grasp the charging timing! The USB rechargeable headlight has a built-in large-capacity battery and can be repeatedly charged by connecting it to a battery or adapter. 2A USB Type-C charging supports much faster quick charging than the conventional 1A, and you can charge it from a mobile phone charger, computer, mobile power supply, or any device with a USB port, so you don't have to waste money buying batteries. Shipping is planned via Takkyubin Compact, but this may be subject to change.
