The official definition of color temperature is“Absolute boldface with different temperatures to produce different colors,” we use [ Kelvin ] said, the single temperature is K, 1 color temperature is 1k. We often have those color temperature, we see in the application of daily life lamps and lanterns use only three color temperature, one is 3000K (warm light) , the other is 6500K (white light) , the other is in the dimmable lamp when the two light together to open the mixture out of 4000K (neutral color) . Does lamp have these two kinds of color temperature only? If we look closely, how does he define warm white light, white light, and neutral light? Does he accurately indicate their values, so that we can get the same color every time we buy it? Actually, we can, let’s take a look at them one by one. Please be patient and read through them. Only by knowing the color temperature can you know what color you want
Now, with the improvement of purchasing power and the specialization of applied scenes, people have been gradually exposed to more color temperature, more color temperature to join us to have a more reasonable lighting environment. (whether or not you only have these two colors in your online or physical store, the problem is that leds were introduced around 2010, and as the market saturates and competition intensifies, more colors will be released to gain a competitive edge.)

In figure 1, I enumerated the color-temperature relationships from 1000k to 10000k in an attempt to let people know their color relationships. The color temperature is the same as the real thing

The second picture of a more detailed classification of color temperature, let us more intuitive and detailed observation of color temperature and color changes. (images collected on the web)
Here are some examples of common light source color temperatures:
1700k: Match Light
1850k: Candles
2800k: the common color temperature of tungsten lamps (incandescent lamps)
3000k: the common color temperature of halogen lamp and yellow fluorescent lamp
3350k: Studio“CP” light
3400k: Studio LAMP, camera floodlight (not flash) , etc. .
4100k: Moonlight, light yellow fluorescent lamp
5000k: Daylight
5500k: average daylight, electronic flash (varies by manufacturer)
5770k: effective solar temperature
6420k: Xenon arc lamp
6500k: the most common white fluorescent lamp color temperature
9300k: TV screen (analog)

Photo 3 is our real photography, ordinary light bulb color temperature of 7350K, through observation we found that color temperature of more than 5700K color has begun to turn blue, we currently use yellow light (3000K) , white light (6500K) is our best choice. I found some industry tips for applying color temperature below

Warm color light, neutral color light, cool color light on the human heart
Warm Color Light
The color temperature of warm color light is below 3,300 k. the color temperature of warm color light is similar to that of incandescent lamp. The color temperature of about 2,000 K is similar to that of candlelight. Red light has more components, which can give people a feeling of warmth, health, comfort, and more desire to sleep. Apply to families, homes, dormitories, hotels and other places or lower temperature; a period of time before going to bed will be adjusted to warm color light is better, the lower the color temperature can maintain the secretion of melatonin.
Neutral Color Light
Its color temperature in 3300K to 5000K, neutral color due to soft light, people have a pleasant, comfortable, serene feeling. Applicable to shops, hospitals, offices, restaurants, restaurants, waiting rooms and other places.
Cool Color light
Its color temperature is above 5000K, the light source approaches the natural light, has the bright feeling, causes the human energy to concentrate and is not easy to fall asleep. Suitable for offices, conference rooms, classrooms, drawing rooms, design rooms, library reading rooms, exhibition windows and other places; a period of time before going to bed using cold light will increase the difficulty of falling asleep and the possibility of illness, therefore, the current popularity of white LED street lamps, in fact, harmful to public health
