The ACEBEAM BK10 bike light is specially designed to be the brightest safety light in accordance with the STVZO standard. Being equipped with XHP35 HI LED, powered by the latest user replaceable 21700 battery with a high capacity of 5100mAh, this impressive bike light 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 focuses the beam on the road without blinding the oncoming pedestrians and drivers. The single button allows an easy and intuitive operation to cycle through any outputs; the Micro-USB function at the backside is for quick and convenient recharging. IP65 rated protection assures BK10 with rain resistance and dustproof. ACEBEAM BK10 provides you with a professional and complete bicycle lighting solution.
Acebeam BK10 Features
The BK10 puts a lot of light in a tightly-focused beam on the road ahead, with enough spill to illuminate road signs. In that way, it resembles my B&M dynamo lights, but with fewer artifacts and greater brightness. Not really suited for off-road riding unless you supplement it with a floody light. The handlebar mount, by contrast, has a cheap feeling to it, though probably adequate. Acebeam doesn't seem to sell standalone mounts to put on multiple bikes (I emailed Acebeam about this and never received a response). Luckily the light has a 1/4-20 threaded hole on the bottom, so you can use camera mounts or gopro mounts with adapters.
