[Super High Brightness]: Our bicycle lights boast a maximum brightness of 1600 lumens (actual lumens), rivaling the intensity of motorcycle lights (refer to the first video on the page). With a beam range extending up to 300-500 meters, these lights feature 5 LEDs that offer 5 lighting modes: Low, Medium, High, Flash, and Extremely Bright, catering to a variety of brightness requirements. The taillight, on the other hand, has a brightness of 50 lumens and comes with four lighting modes. [5200 mAh High Capacity Battery]: Equipped with 2 x 5200 mAh Li-ion batteries, our USB rechargeable bike light ensures extended usage; up to 4 hours in “High” mode and up to 16 hours in “Low” mode. The headlight includes a charge indicator screen that displays the remaining power in real time. To activate the light, simply press and hold the power button for 5 seconds, switch the “L” to any number, and you’re ready to go. [USB Charging and Discharging]: With the included Type-C cable, you can easily charge your bicycle headlight via any USB port. Additionally, in case of an emergency, the headlight can double as a power bank to charge your phone. [IPX6 Waterproof]: Constructed with high-quality aluminum alloy, the shell is not only sturdy and durable but also features a highly secure attachment mechanism for the handlebar. The IPX6 waterproof rating ensures that the light can be used round the clock, even in rainy or foggy conditions.
