K1C Series PSX26 LED Headlight Bulb for Cars and Trucks

Universal for Cars and Trucks

K1C Series PSX26 is designed for vehicles that use the PSX26 bulb type and is positioned as a practical LED headlight upgrade for both passenger cars and light-duty trucks. The focus is broad compatibility and a predictable installation experience for workshops, distributors, and fleet users who support multiple vehicle platforms. Polarity protection helps reduce installation risk where plug orientation can vary, lowering avoidable troubleshooting and helping the retrofit process stay efficient. For wholesale customers, this compatibility-focused design supports cleaner product selection and consistent installation outcomes across common PSX26 applications.

Powerful Performance

The light engine uses four GC-7035 LED chips and targets a 360° beam angle specification to support consistent light distribution in suitable headlamp optics. Electrical operation is rated at DC 9–36V, matching typical automotive electrical environments, and input current is listed as 5.0±0.5A at 13.2V to describe operating draw under a standard reference point. Output is provided in both initial and stable states to reflect real use after the bulb has been running. Rated power is 70W per bulb, with an initial measured power of 68.14W and a stable running power of 61.68W at 30 minutes. Lumen output is also expressed in a practical way, with a theoretical figure of 6000 lumens, an initial measured output of 5948 lumens per bulb, and a stable value of 5016 lumens per bulb at 30 minutes. Color temperature is rated at 6500K with a ±500K tolerance for a crisp white beam appearance.

Heat Dissipation System

Thermal management is built around a combined cooling architecture using dual copper heat pipes plus active airflow. Copper heat pipes help transfer heat away from the LED heat source efficiently and spread it into the aluminum structure, reducing localized hot spots that can accelerate lumen drop. A silent fan supports airflow through the heat sink area, which becomes especially valuable during idling, slow driving, or warm ambient temperatures where passive cooling is less effective. This design helps the bulb reach a steady operating point and maintain more consistent brightness during extended night driving, delivering performance that remains usable over time rather than only at startup.

Integrated Die-Casting Structure

The bulb assembly is built around a robust aluminum structure that provides durability and thermal mass for real automotive duty cycles. High-brightness LED chips are integrated into a compact layout designed to remain stable under vibration and temperature cycling. The PSX26 version is specified with a non-adjustable chuck, keeping installation orientation fixed for the intended fitment geometry and reducing setup variability during installation. This fixed indexing approach supports repeatability for workshops by minimizing manual adjustment and allowing installers to focus on correct seating and proper headlamp aiming.

External Intelligent Driver

An external intelligent driver is used to regulate current delivery to the LED chips. Keeping the driver outside the main bulb body helps reduce heat exposure for sensitive electronics and supports steadier regulation during extended operation. Stable current control also helps the transition from initial output to stable output remain predictable, which matters for users who judge performance after the lamp has been running for a period of time. The external driver layout offers additional flexibility in tight headlamp cavities because the driver can be positioned where space allows rather than being confined to the hottest area directly behind the emitter.

Precise Cutoff and Road Coverage

The beam concept emphasizes controlled road coverage with an anti-dazzle intent. A cleaner cutoff helps keep light focused on the road surface and reduces stray upward spill that can contribute to glare when there is oncoming traffic. Controlled distribution supports clearer lane-edge visibility and more organized illumination, improving comfort while maintaining practical forward coverage. With correct installation and proper aiming, the result is a beam pattern that supports both visibility and driving comfort in mixed traffic environments.

Low Beam and High Beam Performance

Low beam performance is intended to deliver a defined boundary and balanced foreground illumination for comfortable night driving. High beam performance is intended to provide stronger down-road reach while maintaining practical spread for roadside awareness. This combination supports mixed driving conditions, where low beam must remain controlled in traffic and high beam must provide meaningful reach on darker roads. When installed in suitable optics and aimed correctly, these patterns help deliver usable visibility improvements rather than scattered light that looks bright but performs inconsistently.

Compliance

The product is marked for CE and RoHS compliance, supporting common distribution requirements and documentation expectations in many markets. These marks can help streamline procurement and listing workflows for wholesalers and resellers who prefer recognizable compliance identification when stocking and selling LED headlight upgrades.

Built for Everyday Use

K1C Series PSX26 combines clear performance figures, a 6500K white output target, and a cooling system built around dual copper heat pipes, a silent fan, and an aluminum structure. The external intelligent driver supports stable current delivery, while polarity protection reduces installation risk across varied vehicle platforms. With controlled road coverage intent and CE and RoHS compliance, this PSX26 LED headlight bulb is positioned as a practical option for daily driving, workshop retrofits, and wholesale distribution. Warranty coverage is 18 months, supporting regular use in both personal and professional vehicle applications.
