11:57The reviewer discusses the Magicshine MJ-906S bike light, which is designed to be wired into an e-bike system. He explains that out of the box, the light is not in e-bike mode and can draw too much power, causing the e-bike system to shut down. He had to put it into e-bike mode by holding the button for eight seconds. In e-bike mode, the light outputs about 2800 lumens on high, which is less than its maximum but still bright.
