Introducing the IPF LED Fog Lamp Bulb F Series H3 2400K / 6500K, designed to provide optimal lighting for fog lamps with the choice of two emission colors, 2400K and 6500K. These bulbs offer compact size, efficient heat dissipation, and superior light distribution, making them ideal for various fog lamp applications.

**Key Features:**

1. **Ultra-Small Design:** These bulbs are specifically designed to fit the ultra-small H3/H3C lamp types commonly found in commercial vehicles and low-model passenger cars. Despite the limitations of the small bulb shape and lamp structure, IPF has optimized the design for a size almost identical to a halogen bulb.

2. **Optimal Light Distribution:** The light emitting surface's shape and dimensions have been optimized for fog lamp use, ensuring ideal light distribution with an emphasis on practicality. This design achieves a clear cutoff line and minimized glare, providing excellent visibility in foggy conditions.

3. **Choice of Emission Colors:** Two emission colors are available: 

   - *2400K (Kelvin) Yellow Emitting LED (F134FLB):* This option emits a deep yellow light unique to IPF without the need for a yellow filter, eliminating reflections on the light reflector surface and maintaining high luminous flux.

   - *6500K (Kelvin) White Emitting LED (F131FLB):* This option emits a beautiful blue-white light that matches the IPF LED headlamp bulb. It provides high visibility for safe nighttime driving.

4. **Compact and Efficient Design:** These bulbs incorporate two key technologies for compactness:

   - **Dual CPS (Dual Copper Post Structure):** This patented design features two large LED copper substrates placed back-to-back, wrapped in a highly thermally conductive LED body. This structure efficiently dissipates heat while keeping the bulb thin and compact.

   - **High Thermal Conductivity Aluminum Die-Cast Body:** The bulb body uses high thermal conductivity aluminum die-cast alloy, optimizing the shape to maximize brightness within a compact size. The design also emphasizes IPF's uniqueness.

5. **Cutting-Edge Technology:** IPF's unique bulb shape replicates the filament shape of halogen bulbs, achieving a sharp cutoff line that is faithful to the original halogen bulb's performance.

6. **Electromagnetic Compatibility (EMC) and Safety Features:** The bulbs come with a small, reliable constant current driver unit that ensures stable brightness even in situations where voltage may drop, such as during idling stop. It operates at just 7W, contributing to energy savings compared to halogen bulbs (55W). These bulbs also feature high EMC performance, incorporating a high-performance noise filter and various safety functions, including electrostatic/pulse protection and over/under voltage protection. They are compatible with 24V vehicles.

7. **Vehicle Inspection Compliance:** These bulbs are designed as LED conversion kits for genuine halogen and IPF halogen fog lamps. However, please note that using them with lamp types other than H3/H3C may not meet vehicle inspection standards or could result in product malfunction.

Upgrade your fog lamps with the IPF LED Fog Lamp Bulb F Series H3 2400K / 6500K to enjoy enhanced visibility in foggy conditions, reduced glare, and the choice of emission colors to suit your preferences. These bulbs are designed to meet high-quality standards, offer durability, and provide added safety during nighttime driving.
