The CYT 40W LED H4 bulb is a type of automotive headlight bulb designed to replace traditional halogen bulbs. Here's a breakdown of its key features and specifications: ### Key Features: 1. **Power Consumption**: - **40 Watts**: The bulb consumes 40 watts of power, which is typical for high-performance LED headlights designed to provide bright, efficient lighting. 2. **LED Technology**: - **LED Chips**: Utilizes advanced LED chips, likely from reputable manufacturers such as Cree, Philips, or Osram, which are known for their high efficiency and brightness. 3. **Brightness**: - **Luminous Flux**: Often, these bulbs provide a high luminous flux (measured in lumens), typically around 4000-8000 lumens depending on the specific model and LED chip used. This is significantly brighter than standard halogen bulbs. 4. **Color Temperature**: - **5000K to 6500K**: The bulb usually emits a bright white light with a color temperature ranging from 5000K (daylight white) to 6500K (cool white). This color range is ideal for visibility and mimics natural daylight. 5. **Beam Pattern**: - **H4 Socket**: Compatible with vehicles using H4 sockets, it features a dual-beam pattern for both low and high beams, providing versatility in different driving conditions. 6. **Heat Dissipation**: - **Cooling Mechanisms**: Equipped with advanced cooling systems such as heat sinks or cooling fans to manage heat generated by the LEDs and ensure a long lifespan. 7. **Durability**: - **IP Rating**: Likely to have an IP65 or IP67 rating, making it resistant to dust and water, suitable for various weather conditions. - **Long Lifespan**: LED technology generally offers a longer lifespan compared to halogen bulbs, often lasting over 30,000 hours. 8. **Energy Efficiency**: - **Low Power Consumption**: Despite its high brightness, the LED bulb is energy-efficient, reducing the load on the vehicle's electrical system. ### Applications: - **Automotive Use**: These bulbs are primarily used in cars, motorcycles, and other vehicles that require H4 bulbs for their headlight systems. ### Advantages over Traditional Halogen Bulbs: 1. **Brightness**: Provides much brighter light output, improving nighttime visibility. 2. **Energy Efficiency**: Uses less power, which can be beneficial for the vehicle’s electrical system. 3. **Longevity**: Longer operational life compared to halogen bulbs, reducing the need for frequent replacements. 4. **Cooler Operation**: Generates less heat, which helps in maintaining the integrity of the headlight housing and surrounding components. 5. **Improved Aesthetics**: The bright white light enhances the look of the vehicle and provides a more modern appearance. ### Considerations: - **Compatibility**: Always check if the bulb is compatible with your vehicle's headlight housing and electrical system. - **Installation**: Some LED bulbs might require additional adapters or modifications for proper fit and performance. ### Example Products: 1. **CYT LED H4 40W Headlight Bulb**: - Voltage: DC 12V-24V - Power: 40W - Lumens: Approximately 4000-8000lm - Color Temperature: 6000K (Cool White) - Waterproof Rate: IP67 - Lifespan: Over 30,000 hours - Cooling: Built-in cooling fan 2. **Generic LED H4 Bulbs**: - These come in various power ratings and designs, typically offering similar specifications to the CYT 40W LED H4 bulb.
