A classic bike light with a modern twist, the Classic Drive 500+ front light beams 500 lumens (up to 80 hours of runtime) via a single high-output LED emitter. It's built around a sleek cylindrical housing that offers a compact and lightweight form factor. Its waterproof USB-C charging capability is convenient for recharging (cable not included). The machined aluminum construction ensures durability and efficient heat dissipation. Rigorously tested to IPX7 Waterproofing standards, it is built to withstand various weather conditions. Choose from six different output modes, from the highly disruptive Daytime Flash mode to the long-lasting 80-hour runtime in Femto Mode. The Infinite Light Power Pack+ compatibility offers versatility and extended runtimes. The Lezyne Infinite Power Pack+(coming soon!) is engineered to be compatible with our USB-C LED lights to extend runtimes. The original Infinite Light Power Pack is not compatible with this light.Specifications:- Max Lumens: 500- Max Runtime: 80 hours- Battery Capacity (mAh): 1900- Recharge Type: USB-C- Weight: 95g- Dimensions: 83mm, 27mm, 45mm- Features: IPX7, Daytime Flash, Infinite Light Power Pack+
