Introducing the IPF LED Head Lamp Bulb F Series, a state-of-the-art solution that combines mature LED light distribution technology with enhanced luminous flux maintenance, brightness, and perfect light distribution. These bulbs are designed to provide safe and comfortable night driving with impeccable lighting performance.

**Key Features:**

1. **All-in-One Design:** The IPF LED headlamp bulb F Series is an all-in-one model that features a dedicated design for various valve types, including H11, HB3/4, and HIR2. It offers a combination of "bright and wide light distribution" and ease of installation.

2. **Excellent Luminous Flux Maintenance:** These bulbs achieve a total luminous flux of 5,000 lumens, approximately 138% brighter compared to conventional products. This exceptional brightness is maintained over time, ensuring sustained illumination during use.

3. **Perfect Light Distribution:** The bulbs incorporate advanced technologies to balance light distribution and brightness. This includes an optimal heat dissipation structure to efficiently manage heat generated by the LED chips while maintaining a slim design.

4. **Three Key Technologies:**

   - **Dual CPS (Dual Copper Post Structure):** This patented technology employs copper boards in the LED substrate and an evolved "Dual CPS" design. It features two large LED copper substrates placed back-to-back, efficiently dissipating heat generated by the LEDs, ensuring a thin and compact design.

   - **High Thermal Conductivity Aluminum Die-Cast Body:** The LED body uses high thermal conductivity aluminum die-cast alloy, optimizing its shape to enhance heat dissipation.

   - **High-Performance Large Electric Cooling Fan:** The F Series incorporates a large Φ40mm cooling fan for efficient bulb cooling, preventing overheating and ensuring longevity.

5. **Efficient and Reliable Driver Unit:** These bulbs utilize a newly developed SEPIC (Single Ended Primary Inductor Converter) driver circuit, offering compact size, high reliability, and low noise. They are compatible with various vehicle types, including 24V vehicles.

6. **Electromagnetic Compatibility (EMC) and Safety:** The bulbs feature optimized PCB patterns and a high-performance noise filter to achieve high radio noise suppression. Additionally, they include safety features like electrostatic/pulse protection, over/under-voltage protection, and over-current protection to meet strict automotive standards.

7. **Easy Installation:** With an all-in-one design, these bulbs are easy to install. They require approximately 1 thumb's depth (25mm) to replace a genuine halogen bulb and around 5 fingers (100mm) to remove the bulb from the headlamp. In cases where space is limited for bulb removal, it may be necessary to remove the headlamp itself.

8. **Vehicle Inspection Compliance:** The bulbs are designed to meet vehicle inspection standards, ensuring they are suitable for road use.

Upgrade your vehicle's lighting with the IPF LED Head Lamp Bulb F Series to experience superior brightness, perfect light distribution, and enhanced safety during nighttime driving. With compatibility for various valve types and a focus on reliability, these bulbs provide peace of mind for your journeys.
