K3C-9005 LED Headlight Bulb 120W High Power 6500K 11000LM

The K3C-9005 is engineered for drivers and installers who want maximum on-road brightness from a compact, easy-fit 9005 socket bulb. It centers on a high-output architecture that pairs quality GC-7545 LEDs with a robust 9–32 V electrical platform. The light color is a crisp 6500 K white, aimed to deliver clear contrast on road signs, lane markings, and the verge. Output is serious: the bulb is rated at 120 W and up to 11,000 lumens, while measured data shows an honest initial 120.1 W with 10,718 lm and a stable 83.28 W with 7,794 lm. This blend of headline power and sustained brightness is the foundation of the product.

High Power and Brightness for Real Visibility

At switch-on, the 120 W drive pushes the emitters to full intensity so the beam comes up instantly. The 6500 K color temperature produces a clean white output that helps edges stand out at night. Because the 9005 base is widely used for high-beam positions and auxiliary forward lighting, the strong center intensity and broad spread are beneficial on open roads and in rural environments where reach and coverage matter.

Technical Data that Fits and Performs

The light source uses 4PCS GC-7545 LEDs arranged to deliver a 360° light-emitting structure, enabling strong road coverage when installed in the 9005 socket. The electrical system accepts DC 9–32 V, so the bulb works across passenger vehicles and many commercial platforms. It is polarity sensitive, ensuring correct orientation during installation, and an adjustable chuck helps the installer fine-tune the seating depth and rotational position for optimal focus inside the headlamp housing.

Heat Dissipation System for Stable Output

High output demands efficient thermal control. The K3C-9005 uses dual copper heat pipes to move heat rapidly away from the LED core to the heat sink. A dense fin heat dissipation structure increases surface area so heat transfers to the air quickly. Working with these components is a silent fan that accelerates airflow through the fins while keeping noise to a minimum. Under continuous night driving this system helps hold brightness closer to its initial level and reduces the rate of lumen drop.

Sharp Cutoff and Wide Road Coverage

The optical layout is designed for clean beam control. In compatible headlamp housings, you’ll observe a precise, well-focused beam pattern with a sharp transition that keeps glare in check. Forward illumination shows solid reach down the center with generous shoulder fill, giving drivers better definition of the lane, roadside markers, and approaching curves. The result is confident visibility that balances distance and width.

Electrical Compatibility and Easy Setup

The bulb’s wide input range means it can handle typical voltage fluctuations during engine start and alternator load changes. Current draw is measured at 9.1 ± 0.7 A @ 13.5 V. The two-wire connection and adjustable chuck simplify installation for shops and DIY users alike. Once locked in place and aimed correctly, the bulb produces stable output with a consistent 6500 K color.

Tested Quality and Compliance

Each unit is produced with documented conformity and environmental compliance, including CE and RoHS. These credentials support wholesale distribution and fleet deployment, providing assurance for import processes and quality audits.

With its combination of headline power, efficient thermal engineering, controlled beam performance, and recognized certifications, the K3C-9005 offers a strong upgrade route for vehicles using the 9005 socket. It is built to deliver bright, clear forward lighting and to keep that brightness steady on the road.
