The roll-off-your-tongue MJ-906S from Magicshine is a compact yet bright light with a vast array of beam strengths and a number of beam patterns. Daytime running through to ‘burn all the retinas in a mile radius’ amounts of light (4,500 lumens) are pumped out by the two main LEDs, with backups providing daylight riding (DLR) capability.
One button on top lets you toggle through the modes, while the light unit itself is attached to bar and helmet alike, via a Garmin-style quarter-turn bracket. The supplied battery is charged (and also outputs, should you wish) via USB-C, and has a capacity of 10,000mAh for up to 50 hours of burn time. Battery indicator levels are present too.
However, what’s really smart is the electric bike integration. Yes, this light can be integrated in to your ebike’s power supply, so you’ll never forget to charge your light battery again (unless you count your ebike battery as your light battery). It works with Brose, Bosch, Shimano and Yamaha systems.
