LIU HJG Original 300W H4 LED Headlight Bulb Set | High Low Beam 6500K White | Set of 2

High Output LED Headlight System

The LIU HJG Original H4 LED Headlight Bulb Set includes two 150W LED bulbs, delivering a combined 300W total output. Designed for vehicles using an H4 holder, the system provides high beam and low beam functionality through advanced LED optics and CSP chip technology.

6500K White Light Output

Each bulb produces a 6500K white beam designed for night driving and road illumination. The optical design focuses light efficiently to support a balanced beam pattern and consistent road coverage.

Korean CSP LED Chip Technology

The bulbs use double-sided Korean CSP LED chips designed to provide strong illumination, beam focus and light penetration. Each bulb produces approximately 15,000 lumens, offering substantial light output for night driving applications.

Laser Calibrated Beam Alignment

During manufacturing, each LED bulb is laser calibrated and aligned with its base to help maintain accurate beam positioning and balanced light distribution after installation.

High and Low Beam Functionality

The H4 configuration supports both:

• High Beam
• Low Beam

allowing a single bulb to perform both lighting functions.

Advanced Cooling System

Each bulb is equipped with:

• 12000 RPM Turbo Cooling Fan
• Cold Pressed Aluminum Radiator
• Smart Aerodynamic Cooling Vents
• Advanced Thermal Management System

These components work together to help control operating temperatures during extended use.

Die Cast Aluminum Construction

The housing is manufactured from die-cast aluminum, providing structural durability and improved heat dissipation compared to standard plastic-bodied alternatives.

Waterproof and Dust Resistant Protection

The bulbs feature:

• IP68 Waterproof Rating
• Waterproof Driver
• Waterproof Connectors
• Dust Resistant Construction

Designed for reliable operation in rain, dust and varying environmental conditions.
