As a helmet light, the 900S works quite well. It’s surprisingly bright and the beam pattern strikes a nice balance between concentrating light in the center and diffusing it along the periphery.

Overall, we found the Magicshine MJ-900S to be an affordable and bright bike light setup. At only $69.99, the MJ-900S offers an impressive 1500-lumen output which is more than enough for nighttime riding. While the wired setup is less convenient than all-in-one commuter-style lights, it results in a more compact headlight with a versatile battery pack. The MJ-6112 battery pack has robust connector designs as well as power bank functionality for charging other devices. With this updated design, we’re also happy to see the Garmin-style mount and integrated DRLs that allow the light to be used in the daytime. Compared to the previous generation, the MJ-900S is an excellent upgrade that brings brighter output and modern features.

Paired with the light is our custom design battery pack MJ-6112. MJ-900S is an upgrade and improved version of the original classic MJ-900 which has sold millions of units around the world.


It continues the MJ-900’s compact, lightweight, and high-output design. The cover lens, LED light source, installation, and battery capacity have all made huge forward strides. Max output is now able to reach 1500 lumens, thanks to the latest upgrades. Expanded upon the already huge and varied rider base. Aside from its main function, some road-friendly safety features have been added, an independent DRL coupled with side lighting to enhance passive visibility.
