If conquering tough mountain trails, peddling through luscious forests at night is your thing, then you fully appreciate the thrill of hardcore night time mountain biking. Here at Magicshine we are all about enhancing that experience. Check out our latest, the MJ-902S. This powerhouse uses two super power efficient LEDs with a combined max output of 3,000 lumens. Equipped with high efficiency, high transmittance optical lenses, producing the perfect beam pattern for your nightly adventures. Illuminating every obstacle in your path: rocks, roots, tree branches and water puddles are revealed well in advance and in detail. In efforts to maximize the versatile purposes of the MJ-902S, we have added independent Daytime Running Light, side lighting and anti-glare to fully round out MJ-902’s active and passive safety features under all weather and road conditions. MJ-902S is powered by 7.2V 7,000mAh super-capacity battery pack, providing up to 42 hours of continuous runtime. Aside from the full beam mode, each LED is able to activate on its own. This not only allows for maximum battery saving potential, but further adds to more riding scenarios with various level of lighting needs. Onto installation, the MJ-902S adopts the universal Garmin quad-lock style mounting mechanism, literally one second light head installation and removal. Aluminum alloy out front mount and helmet mounting options available separately. One button control for on/off and all brightness settings, large area silicone button is bright black, quite easy to see at night and press with gloves. Built in smart thermal management system and a very large area heat sink will ensure consistent, maximum output while keeping the bike light in optimal condition. To enter the E-bike compatible mode, simply press and hold the power switch for 8 seconds. The button will flash quickly as indication. MJ-902S is compatible with most mainstream motors such as ones from Bosch, Brose, Shimano and Yamaha. The bike light adjusts its output power automatically based on the input voltage(within a 6V-12V range.) When the sun sets, the MJ-902S will switch on its own from daytime running mode to night time, full power mode to illuminate your path.
