The ACEBEAM BK10 bike light is specially-designed to be the brightest safety light in accordance with STVZO standard. Being equipped with XHP35 HI LED, powered by the latest 21700 cell with super high capacity of 5100mAh, this impressive illuminator can emit up to whopping 2000 lumens brightness. The optical PMMA lens makes the beam spot with high light efficiency, eligible for the latest international spot requirement. The rectangular speckle does not only illuminate the entire ride, but also focus the beam on the road without dazzling the oncoming pedestrians and drivers for safety. The single button allows easy and intuitive operation to cycling through any outputs; the Micro-USB function at the back side is for quick and convenient re-charging. IP65 rated protection assures BK10 with rain resistance and dust proof. ACEBEAM BK10 provides you with a professional and complete bicycle lighting solution. By Acebeam.
