Overview: Precision 1:1 Halogen Filament Match for Superior Fog Penetration
The H3-2L is an advanced miniature automotive LED bulb engineered specifically to replace traditional 35W / 55W H3 halogen fog light bulbs. Featuring a true 1:1 physical size and optical focal point design, the H3-2L matches the exact filament location of OEM H3 bulbs. This ensures razor-sharp light cutoff and maximum beam throw inside factory reflector and projector fog housings without creating blinding glare for oncoming traffic.
Constructed from a solid one-piece 6063 aviation-grade aluminum CNC body, heat generated by the dual CSP 1860 automotive-grade emitters is conducted instantly down to the heavy-duty flange base. Consuming only 7.0W while delivering 700 true lumens of high-density illumination, the H3-2L runs substantially cooler than factory 55W halogens, preventing reflector burn and lens yellowing over extended driving sessions.
Technical Dimension Blueprint & Laboratory Light Pattern
The H3-2L is exclusively designed and optically calibrated for Automotive & Motorcycle Front Fog Lights, Daytime Running Lights (DRL), and Low-Speed Equipment Auxiliary Lamps:
- Dedicated Fog Light Optical Design: Engineered at 7W / 700LM per bulb with dual CSP 1860 emitters, it produces a wide, low-cutoff horizontal beam designed specifically to penetrate dense fog, rain, snow, and dust without atmospheric back-scatter.
- Strictly NOT for Main Forward Headlights: This model is NOT intended or certified for primary High Beam / Low Beam driving headlights. Main headlights require 20W–40W per bulb with 2500+ lumens for long-distance highway projection.
- Universal Multi-Voltage Deployment: Available in independent 6-15VDC (for vintage cars, motorcycles, 12V passenger vehicles) and 12-32VDC (for commercial fleets, heavy-duty trucks, industrial electric forklifts, and AGV equipment).
Core Engineering Advantages & Thermal Management
- 1:1 Halogen Filament Geometry: The ultra-narrow 12mm aluminum body positions the CSP chips at the precise mathematical focus of standard H3 fog light housings, eliminating dark spots and beam scattering.
- Instant Thermal Dissipation: Constructed from 6063 aerospace aluminum with high thermal conductivity (approx 200 W/m·K), conducting heat directly through the metal flange without mechanical cooling fans that can jam with road debris.
- Standard PK22s Pigtail Wiring: Equipped with a high-temperature insulated pigtail wire terminated with a standard male spade terminal for direct zero-modification connection to vehicle wiring harnesses.
- Dual Independent Voltage Architecture: Dedicated constant-current IC driver boards for 6-15VDC and 12-32VDC provide unvarying 700LM optical output regardless of vehicle alternator voltage fluctuations.
- Three High-Visibility Color Temperatures: Available in 6500K Xenon White (clean modern look), 3000K Warm White (OEM retro halogen styling), and Amber Golden Yellow (supreme wavelength penetration in heavy rain, fog, and snow).
