9 Elements of Selected LED Car Bulbs

The specifications of LED car bulbs are usually defined based on parameters such as their size, power, voltage, color temperature and brightness. Below are some common LED car bulb specifications:

1. Size: The size of an LED bulb is usually expressed by its diameter, e.g., T10, T15, T20, etc., and these numbers are usually expressed in millimeters. In addition, there are alternative models for halogen bulbs such as H1, H4, H7, etc.
2. Power: The power of LED bulbs is usually measured in watts (W), with common powers such as 3W, 5W, 7W, 10W, 15W, and so on. LED bulbs with higher power usually provide brighter lighting.
3. Voltage: LED bulbs usually operate at 12V or 24V to accommodate different vehicle electrical systems.
4. Color Temperature: Color temperature is measured in Kelvin (K) and indicates the color of the light. Common color temperatures are 3000K (warm white light), 4300K (natural white light), 6000K (cool white light) and 6500K (daylight color).
5. Brightness: Brightness is usually measured in lumens (lm). the higher the brightness of the LED bulb, the better the lighting effect. 6. Lifespan: The brightness of the LED bulb is usually measured in lumens (lm).
6. Life: LED bulb life is usually measured in hours, and high quality LED bulbs can last up to tens of thousands of hours.
7. Beam Angle: The beam angle affects the light distribution and irradiation range, different applications require different beam angles.
8. DIMMERING FUNCTION: Some LED bulbs have a dimming function, which allows you to adjust the brightness to suit different driving environments.
9. Waterproof rating: For LED bulbs used externally, such as headlights and taillights, there is usually a waterproof rating, such as IP65 or IP67, to ensure the reliability of the bulb in harsh weather conditions.
10. CERTIFICATION: High quality LED bulbs usually have international certifications such as DOT (USA), ECE (Europe), etc. to ensure that they meet road safety standards.
    These specifications can vary according to different car models and usage requirements. When choosing LED car bulbs, make sure they are compatible with your vehicle and meet your lighting needs.
