Product Description

The Star Union QD470 is a professional road and gravel headlight system built in the style of top external-battery lights used by endurance and night-ride cyclists.
A compact 900-lumen headlamp sits cleanly on your handlebar, while the powerful external battery pack mounts securely to your bike frame to provide unmatched runtime stability.

The beam uses a modern cut-off design, delivering a clean, wide illumination zone that lights the road ahead without blinding drivers, riders or pedestrians.
Perfect for late-night commutes, long-distance races, gravel exploration and all-weather use.

Equipped with Type-C charging and output capability, the QD470-2 battery pack also functions as a power bank—ideal for keeping your phone, navigation device, or action camera running on long rides.

The system includes a 360° adjustable mount and a wired remote switch, allowing you to fine-tune beam angle and switch modes instantly while maintaining full control of your bike.
