Wuben B2 Bicycle Light 1300 Lumen 280m Throw Rechargeable with 18650 or 21700 Battery Description
The Wuben B2 Bicycle Light 1300 Lumen 280m Throw Rechargeable with 18650 or 21700 Battery is a high-performance bike light designed for night riding, ideal for urban commuting, mountain biking, and road cycling. For example, its 1300-lumen output can illuminate a path up to 280 meters, ensuring visibility on unlit roads or trails during a night ride. With a rechargeable battery (select 18650 or 21700 at checkout), Type-C charging, and a durable build, it offers reliable functionality. Featuring a 5-year warranty, this Wuben B2 for Outdoor Use suits cyclists, commuters, and outdoor enthusiasts.

Powerful Illumination for Outdoor Use
The Wuben B2 features an OSRAM P9 LED with a color temperature of 6500K, delivering a maximum output of 1300 lumens with a beam throw of 280 meters, powered by either a 2600mAh 18650 Li-ion battery (included by default) or an optional 21700 battery (select at checkout). It offers six modes, controlled by a single W button (single click to cycle modes, double click for Turbo or special modes, long press to turn off), with the following lumen outputs and runtimes:

• Turbo: 1300 lumens for 1 hour
• High: 600 lumens for 2 hours
• Medium: 300 lumens for 5 hours
• Low: 100 lumens for 7 hours
• Beacon: Intensity not specified (runtime not specified)
• SOS: Intensity not specified (runtime not specified)
  The flashlight charges via a Type-C USB port in approximately 5 hours (using the 18650 battery), with a battery status indicator (flashing colors to show levels). It is IP68 waterproof (submersible to 2m) and 1.5m impact-resistant, with a 360° rotating bike mount for adjustable beam positioning, though the round beam lacks a hard cutoff, which may cause glare for oncoming traffic, requiring careful aiming. This makes the B2 a versatile choice for outdoor use, though users should be mindful of beam direction and battery rattling with unprotected cells [Ref web:0⁊] [Ref web:1⁊] [Ref web:2⁊].

Durable and Compact Design
The Wuben B2 is constructed from 6061 aircraft-grade aluminum alloy with a Type III hard-anodized finish, available in black, grey, or blue, offering durability for rugged cycling conditions like mountain biking or commuting. It measures approximately 120mm in length (4.72 inches) with a diameter of 25.4mm (1 inch), weighing around 150g with the 18650 battery (weight varies with 21700), making it compact and easy to mount on handlebars (22-35mm diameter). The flashlight features a TIR optic for a combined spot and flood beam, a secure bike mount with a rotating shaft for easy installation/removal, a bonus taillight with a rubber strap (Micro-USB rechargeable), and a battery tube adapter for 21700 compatibility, though unprotected batteries may rattle on bumpy rides, suggesting the use of protected cells or spacers for stability. This makes the B2 a durable, compact choice for outdoor use, though users should ensure battery compatibility for rough terrain.

Designed for Outdoor and Tactical Use
The Wuben B2 Bicycle Light 1300 Lumen 280m Throw Rechargeable with 18650 or 21700 Battery for Outdoor Use is tailored for cyclists, commuters, and outdoor enthusiasts needing a reliable, high-power bike light for night riding, urban commuting, or mountain biking. For example, its 280m throw ensures visibility on unlit trails, while the 7-hour Low mode supports long rides, though the round beam may not comply with road regulations in some regions (e.g., Germany, requiring a shaped beam), and the step-down from Turbo after a short period can limit sustained high output, requiring mode adjustments for longer use. The IP68 rating, sturdy mount, and bonus taillight enhance its utility, but users should avoid direct eye exposure due to its intensity. The B2’s user-friendly design, Type-C charging, and battery compatibility make it a practical choice for outdoor scenarios, offering a balance of power and versatility, though users should plan for battery selection and beam aiming for safety and compliance [Ref web:1⁊] [Ref web:2⁊].
