Wholesale USB Rechargeable Bicycle Front Light

This light is engineered for high‑output visibility while maintaining a compact form factor suitable for OEM integration and bulk procurement. The design focuses on thermal efficiency, reliable power delivery, and robust environmental sealing to meet the demands of daily commuting, off‑road trails, and fleet‑based rental operations.

Technical Specifications

Key Functional Characteristics

Performance stability is achieved through a constant‑current driver that regulates LED current within ±2 % across the battery voltage range, ensuring consistent lumen output from full charge to cut‑off.

• Housing made from 6063‑T5 aluminum alloy with external fins, providing thermal resistance ≤15 °C/W.
• Lens constructed from UV‑stabilized polycarbonate with anti‑scratch hard coating, transmitting ≥92 % of emitted light.
• Integrated motion sensor reduces output to 100 lm after 30 seconds of inactivity, extending usable runtime by up to 40 % in intermittent use.
• Built‑in protection circuitry guards against reverse polarity, over‑voltage, and thermal runaway.

Typical Applications

Urban commuters benefit from the high‑flux output and quick‑release mount, allowing tool‑free installation on handlebars ranging from 22.2 mm to 35.0 mm diameter.

For delivery fleets, the IP67 rating ensures operation in heavy rain and spray, while the programmable flash modes (steady, pulse, strobe) can be configured to meet local visibility regulations, reducing the need for ancillary lighting accessories.

Quality Control & Testing

Each unit undergoes a 100 % functional test before packaging, verifying luminous flux, current draw, and firmware response.

• Luminous flux measured in an integrating sphere with traceable calibration (±1 % uncertainty).
• Thermal shock cycling: –30 °C to +80 °C, 10 cycles, optical deviation <5 %.
• Impact test: drop from 1.5 m onto concrete, housing inspected for cracks or ingress.
• Salt‑spray exposure per ASTM B117 for 96 hours, contact resistance increase <10 mΩ.

Customization Options

OEM buyers can tailor optical, electrical, and branding aspects to align with product lines or regional specifications.

• Color temperature choices: 4000 K (neutral) or 6500 K (cool white) LED bins.
• Beam pattern options: wide‑flood (≥100°) for off‑road, narrow‑spot (≥10°) for long‑range road use.
• Battery capacity scalable from 1500 mAh to 3000 mAh, affecting runtime proportionally.
• Laser‑etched or silk‑screened logo on housing, minimum order quantity 500 pcs.
• Optional auxiliary USB‑A port (5 V/1 A) for external power‑bank charging.

Packaging & Lead Time

Standard packaging includes an anti‑static bag, individual printed box, and a master carton of 20 units (carton size 380 mm × 260 mm × 150 mm, gross weight ≈8.5 kg).

Typical production lead time is 18‑22 working days after receipt of purchase order and approved samples; express lanes can reduce this to 12 days for qualifying volumes.
