Recently, many friends are confused with the color temperature of LED headlights, worried that the color temperature above 6000K will not be seen clearly in rain and fog. Today, we will talk about the problem of color temperature.
 The color temperature is not the temperature of light, but the color of light. The color temperature of 1000K-12000K is red, orange, yellow, white and blue respectively.

3000 K: the common color temperature of halogen lamps and yellow fluorescent lamps

4100 K: Moonlight, light yellow fluorescent lamp

5000 K: daylight

5500 K: Average daylight, electronic flash (manufacturer to manufacturer)

6500 K: the most common white fluorescent light color temperature

9300 K: TV screen (analog)

But the color temperature is not just the color of light, it involves penetration, because light is electromagnetic waves, and different colors of light are essentially electromagnetic waves of different wavelengths. The electromagnetic wave range that the human eye can see is visible light, and the wavelength range is generally 360-400 nm ~ 760-830nm. The bluer, the shorter; the longer wavelength passes through the obstacles, the shorter wavelength can carry more information, but are more likely to be disturbed and scattered.
