Night riding demands reliable illumination that balances brightness, power efficiency, and ruggedness. This front‑light module uses a high‑efficiency LED driven by a constant‑current circuit to deliver stable output over a wide voltage range, reducing flicker and extending battery life. Engineers selecting bulk components for OEM assemblies or distributor stock benefit from a design that minimizes part count while meeting common safety‑lighting standards.
| Parameter | Typical Value | Notes |
|---|---|---|
| LED Type | Cool white 5050 SMD | Luminous efficacy ≈150 lm/W |
| Luminous Flux | 300 lm (±10%) | Measured at 25 °C, steady state |
| Beam Angle | 15° ± 2° (spot) + 45° ± 5° (spill) | Provides focused distance illumination with peripheral visibility |
| Operating Voltage | 3.7 V – 5.5 V DC | Compatible with 1× 18650 or 2× AA Li‑ion packs |
| Runtime (High) | ≈2.5 h at 300 lm | Depends on battery capacity; constant‑current driver maintains flux |
| Ingress Protection | IP65 | Dust‑tight, protected against low‑pressure water jets |
| Housing Material | ABS‑PC blend, UV‑stabilized | Impact resistance >5 J (IK07) |
| Mounting Interface | M5 screw hole + rubber strap slot | Fits standard fork crowns and handlebar diameters 22‑32 mm |
| Weight | 45 g (excluding battery) | Contributes < 5 % to typical e‑bike front‑end mass |
Cyclists need a beam that reaches far enough to spot obstacles while providing enough side spill to see the road edge and traffic. The 15° spot core delivers usable illumination beyond 30 m at 0.5 lux, meeting the minimum visibility threshold recommended by many cycling federations. Simultaneously, the 45° spill ensures peripheral awareness without causing glare to oncoming riders, a balance achieved through a precision‑molded polycarbonate lens with internal refractive ridges.
Power consumption stays below 1 W at full output, allowing a modest 2000 mAh Li‑ion cell to sustain rides longer than two hours on high mode. The IP65 rating protects against rain, spray, and dust ingress encountered on mixed‑surface routes, reducing field‑failure rates for bulk‑deployed fleets such as rental bike programs or delivery services.

Each production lot undergoes incoming inspection of LED bins, verifying forward voltage and luminous intensity within defined tolerances. During assembly, automated optical alignment ensures the lens‑LED axis deviation stays under 0.2°, which directly influences beam uniformity. Finished units are subjected to a 30‑minute burn‑in at 40 °C ambient, followed by functional checks of flash modes, low‑voltage cutoff, and sealing integrity via IP65 spray testing.
Statistical process control charts track key parameters such as drive current and luminous flux; any shift beyond 2σ triggers a lot hold and root‑cause analysis. This approach reduces the likelihood of field‑reported dimming or flicker, providing purchasing teams with predictable performance for large‑scale deployments.
Housing color can be adjusted to match brand palettes using pigment‑injected ABS‑PC, available in black, white, safety orange, or custom Pantone matches upon request. Lens geometry offers alternatives: a wider 20° spot for urban commuting or a narrower 10° spot for off‑road trail use, each requiring a corresponding tooling change. Cable length and connector type (JST, Molex, or bare leads) are adjustable to integrate with existing battery management systems or wiring harnesses.
Firmware of the driver can be flashed to alter mode sequencing, enabling programmable daytime running light (DRL) patterns or adaptive brightness based on ambient light sensor input. All customizations are subject to minimum order quantities and tooling amortization, which are discussed during the quotation phase.
Units are packed in anti‑static trays with 50 pcs per inner carton, each carton measuring 380 × 260 × 120 mm and weighing approximately 7.5 kg. Outer cartons consolidate five inner cartons (250 pcs) for palletization, providing a stable load that conforms to ISPM‑15 standards for export. Shock‑absorbing corner protectors and humidity indicator cards are included to monitor transit conditions.
For customers requiring drop‑ship to multiple destinations, we offer kitting services that combine the light with battery packs, mounting hardware, and user manuals into a single SKU. Labeling can include barcodes, QR codes, or custom logos as per the client’s specification.
Standard lead time for stock‑configured units is 2‑3 weeks after receipt of purchase order, assuming material availability of LED bins and housings. Customized orders involving new mold tools or firmware development typically require an additional 4‑6 weeks for tooling approval and pilot run validation. Minimum order quantity for bulk pricing starts at 500 pcs, with price breaks at 2 k, 5 k, and 10 k units.
Quotations are provided upon receipt of technical requirements such as desired lumen output, operating voltage range, connector type, and any regulatory markings (e.g., CE, RoHS). We recommend supplying a short specification sheet or referencing our standard part number to expedite the process.
