H4 Mini LED Projector Lens Headlight Bulbs

1:1 H4 SIZE MATCH

DUAL COPPER HEAT PIPES

SMART CPU CONTROL

OPTICAL PROJECTOR LENS

SUPERIOR NIGHT VISION

Designed for seamless halogen-to-LED upgrades, the H4 Mini Bi-LED Projector Lens Headlight Bulb combines an optical projector lens and customized Tianxin 3570 LED chips into a compact form factor. Delivering 40W on Low Beam (2300LM) and 50W on High Beam (3500LM), it generates a sharp, glare-free cutoff line while utilizing the vehicle’s stock reflector for a restore-to-factory high-beam projection. Advanced thermal technology—including dual copper heat pipes, dynamic CPU temperature control, and a 9000 RPM silent cooling fan—ensures reliable performance and exceptional longevity.

Direct 1:1 Halogen Replacement

Engineered with precise 1:1 size matching for factory H4 halogen bulbs, enabling seamless plug-and-play installation without headlight housing modification.

Customized High-Output Chips

Built with Tianxin 3570 6068mil high-density LED chips to produce 2300LM low beam and 3500LM high beam for exceptional brightness.

Dual Copper Heat Pipe System

Features advanced dual copper heat pipes paired with a 9000 RPM silent fan and CPU thermal control for optimal heat dissipation and long lifespan.

Optical Lens & Adjustable Beam

Integrated optical projector lens provides a sharp, glare-free cutoff line, with adjustable socket screw slots for perfectly horizontal beam tuning.

H4 Mini LED Projector Lens Headlight Features & Applications

Key Features

Dual Optical Beam System: The low beam utilizes an internal aluminum reflector cup and optical glass convex lens for uniform, high-focus light distribution with a sharp cutoff. High beam utilizes the original light reflector to restore factory beam patterns.
Adjustable Cutoff Line: The H4 mounting collar features specialized screw slots, allowing quick angle adjustments to align the horizontal cutoff line perfectly.
Dual Heat Pipe Thermal Management: Premium dual copper heat pipes instantly draw heat away from the Tianxin LED chips to preserve light intensity and prevent thermal decay.
Precision CPU & Active Fan Cooling: Equipped with dynamic CPU thermal protection and a low-noise 9000 RPM cooling fan to guarantee maximum reliability.
1:1 Luminous Point Matching: The light source is positioned to match standard H4 halogen filament locations, optimizing light output in factory headlight assemblies.

Primary Applications

Halogen Reflector Upgrades: Perfect for passenger cars, light trucks, and motorcycles equipped with factory H4 halogen housings that require a sharp cutoff without blinding oncoming drivers.

All-Weather & Daily Driving: Ideal for night commuting, highway cruising, and rainy conditions with clear 5500K–6500K color temperature visibility.

What is your sample policy?

We can supply the sample and the sample charge is refundable according to the next order, please contact us for details.

Do you test all your goods before delivery?

Yes, we have 100% test before delivery.

What is the difference between us and other suppliers?

1)Wal-mart certified manufacture, IATF 16949 quality system.u003cbru003e2)we have strong OEM,ODM production capacity u0026amp; quality management.u003cbru003e3)D series OEM ballast with Emark(E13) certificate.u003cbru003e4)Strong packing capacity to produce product with blister package or color box package.

Will this H4 Mini Lens bulb fit my headlight housing without modifying the reflector?

Yes, it is designed as a direct plug-and-play upgrade for original halogen H4 sockets. The mini lens housing slides directly into the bulb opening without requiring you to bake open or disassemble the headlight assembly.

How do I adjust the beam cutoff line if it appears tilted after installation?

The H4 mounting plate is built with slotted screw holes. You can loosen the retaining screws slightly, rotate the bulb body to align the cutoff line horizontally, and tighten the screws to lock it into position.

Why is the dual heat pipe design important for this projector lens?

Because projector lenses pack high-power LED chips into a compact space, thermal management is critical. Dual copper heat pipes conduct heat away from the chips rapidly, working alongside the CPU temperature control and 9000 RPM silent fan to protect against premature LED decay.

Does this bulb work on both 12V and 24V vehicles?

Yes, it operates within a wide voltage range of DC 9–36V (rated at 13.2V), making it fully compatible with 12V cars, SUVs, motorcycles, and 24V commercial trucks.
