P2 Series H4 LED Headlight Bulbs

The P2 Series H4 is a compact LED headlight solution for B2B programs that need stable output, structured heat management, and an installation-friendly H4 format. It combines four GC-7035 LED chips, a 6500K color temperature, DC 9-32V operation, and a non-polar electrical design. At the center of the product is a five-stage cooling circulation concept designed to transfer, circulate, and release heat through coordinated thermal components.

Instead of relying on a single heat-dissipation method, P2 Series H4 combines a thermal interface, copper heat-transfer path, active fan cooling, aluminum heat-release structure, and circular heat-pipe circulation. This creates a clear cooling story for distributors and product managers who need a compact LED headlight bulb with a more complete thermal-management design.

Silicone Heat Dissipation and Copper Heat Tubes

The cooling path begins around the LED light source. Silicone heat dissipation helps transfer heat away from the LED area, while copper heat tubes carry that heat toward the wider cooling structure. This combination is designed to move thermal energy efficiently from the source rather than allowing heat to remain concentrated around the light-emitting area.

For a compact high-output lamp body, heat transfer near the LED source is especially important. The silicone interface and copper heat tubes form the first part of the P2 Series H4 thermal circulation path, helping prepare heat for distribution through the rest of the cooling system.

Double Ball Bearing Fans

P2 Series H4 uses double-ball-bearing fans to provide active airflow through the lamp body. The fan system helps move air around the internal heat-dissipation structure and supports continuous removal of accumulated heat during operation. Active airflow complements the passive thermal components, creating a more complete cooling approach for the compact housing.

By pairing fan-driven airflow with the copper heat-transfer path, the design helps heat continue moving instead of remaining in one area. This is particularly useful for a headlight product specified with high start power and stable set-level power, where thermal performance needs to work together with electrical output.

Aerospace Aluminum Housing and Cooling Fins

The aerospace aluminum structure provides a durable heat-transfer body for the P2 Series H4 cooling system. Its integrated cooling fins increase the available surface area for heat release, allowing thermal energy to disperse from the lamp body more effectively. The fin structure also supports airflow generated by the double-ball-bearing fan system.

This combination of aluminum construction and cooling fins gives the compact P2 Series H4 housing a practical balance between size and heat-release area. The lamp body is designed to remain space-conscious while still providing a dedicated structure for thermal management behind the headlight position.

Circular Heat Pipe Cooling

Circular heat-pipe cooling completes the P2 Series H4 thermal circulation design. The ring-shaped heat-pipe structure supports heat movement around the heat sink and connects the individual cooling components into a more continuous circulation path. Together with the silicone thermal interface, copper heat tubes, fan system, aluminum housing, and fins, it forms the product's five-stage cooling concept.

This coordinated structure is designed to manage heat generated during operation and help support the declared 74W stable power per set. It gives P2 Series H4 a cooling-focused product identity without relying on a single fan, a single fin section, or a single heat-transfer component alone.

Four GC-7035 LED Chips with 6500K Output

P2 Series H4 uses four GC-7035 LED chips with a 6500K color temperature for a crisp white headlight appearance. High-beam output is rated at 9,600 lm initial and 7,000 lm stable. Low-beam output is rated at 8,200 lm initial and 5,600 lm stable. Keeping these output figures separate gives purchasing teams and catalog managers a clearer basis for preparing technical listings and product comparisons.

The four-chip configuration, 6500K light color, and separate initial and stable lumen data provide a more complete specification picture than a single lumen headline. This makes it easier for wholesale customers to identify P2 Series H4 correctly without placing lumen figures in the product name.

Real Set-Level Power for Sustained Operation

P2 Series H4 is specified with 110W start power per set and 74W stable power per set. This distinction provides a useful performance reference for buyers evaluating both initial operation and stable running conditions. The declared input current is 4 ± 0.4A at 13.5V, while the operating-voltage range is DC 9-32V.

The compact lamp body and five-stage cooling circulation design work together to support stable operation after start-up. This gives the product a clear combination of power data, thermal-management structure, and headlight-specific LED performance for B2B product programs.

Wide-Voltage and Non-Polar Design

The DC 9-32V operating range supports vehicle electrical systems that require a wide-voltage LED headlight solution. Its non-polar design removes the need to distinguish positive and negative plug orientation during connection, helping reduce avoidable installation errors and making the connection process more straightforward.

For distributors, wholesalers, OEM buyers, and private-label programs, the combination of wide-voltage operation and non-polar installation design creates an easy-to-communicate product benefit for catalog descriptions, sales materials, and technical discussions.

Compact Format for Headlight Programs

P2 Series H4 uses a compact body designed for headlamp housings where rear-space consideration can be important. The space-conscious format helps create a practical option for headlight upgrade programs that need structured cooling and defined output data without an oversized rear lamp body.

By combining a compact H4 format, four GC-7035 LED chips, separate high- and low-beam lumen figures, real set-level power data, wide-voltage operation, non-polar installation, and five-stage cooling circulation, P2 Series H4 provides a focused LED headlight solution for wholesale, OEM, and ODM discussions.
