Brand new smart bike light from Magicshine. The MJ-900B looks very much like the original MJ-900 but with a whole lot more tech under the hood. Single XM-L2 LED capable of producing 1000 lumens of maximum actual output. The Bluetooth chip allows for remote control of the bicycle light from most mobile devices. Brightness, flash modes can be customized and saved into “scenes” for fast switching depending on riding conditions. Once custom settings are saved, the top switch button no longer cycle through the factory default brightness settings of 100% 50% 25% and Flash modes. It will be cycling through your customized settings even without your mobile device present.
Battery pack for the MJ-900B has also undergone significant re-design. The MJ-6112 Li-ion pack uses 2×18650 LG cells to supply 2.6Ah of power, capable of 2.2 hours of continuous runtime under max brightness. It can also be used as an emergency USB power bank providing 5V/2A output for your mobile devices. Next to the USB port is the Micro USB charging port and 3 green LED power indicator lights, with each light representing roughly 30 percent remaining capacity.
