MJ-902B reviewed by Road.cc
——It all feels premium – the connectors snap home firmly, and the body of the battery and light look and feel well made. The battery pack has a rubber backing and mounts on your frame using wide Velcro straps, with enough spare to wrap securely around the largest of box-girder frames. There’s a rubber seal around the inside, and the connector to the light is a robust circular push-fit – both survived several pressure-washings with zero ingress. Rock-solid battery attachment and connections. Near-infinite customizable options. Rock-solid hardware connectivity. Useful as general external battery pack for charging things.
MJ-902B bicycle light redesigned with Bluetooth chip, more efficient cooling and multi-functional battery pack, the MJ-902B Bluetooth bicycle light.
The MJ-902B has always been a versatile bike light due to its small size and light weight design. At exactly the same size as the MJ-900, the 902B puts out much more lumens making it suitable not only for road but MTB, Enduro riding as well. The two XM-L2 LEDs are capable of producing a maximum of 1600 lumens of actual output. Now without the accompaniment of a taillight and wireless remote, the MJ-902B can be easily controlled via your mobile device. There are 4 pre-programmed lighting modes, constant, SOS, Flash and Warning. Each can be customized with a brightness level from 1-100%. Your custom settings can be saved and grouped for later use. Once the settings are saved, the top power switch on the light head no longer cycle through the factory brightness settings, but your own.
Totally redesigned USB rechargeable battery pack MJ-6116 has a max capacity of 5.2Ah from its four 18650 LG Li-ion cells. Providing 2.3 hours of max runtime on its brightest setting. Much like the MJ-6112, the 6116 can also acts as an emergency power bank through its 5V/2A USB port. Streamlined design and high quality of the material make for a durable, weatherproof and high performing unit. For the weight sensitive road riders, the light head weighs in at 51.5g while the battery pack at 287 g.
