Color Temperature And Influence of Lights

Color temperature is a measure of the light color of a light source,its unit of measurement is Kelvin.
In physics, color temperature refers to heating a standard black body..When the temperature rises to a certain extent, the color gradually changes from dark red to light red, to orange, to yellow, to white, to blue. When a light source is the same color as the black body, we call the absolute temperature of the black body at that time as the color temperature of the light source.
Color temperature is generally divided into warm white (2700K-4500K), positive white (4500-6500K), cold white (6500K or more).

The photo above lists the color temperature relationship from 1000K to 10,000K, you can know their color relationship from it.

This picture divides the color temperature levels in more detail, allowing us to observe the color temperature and color change more intuitively.
Here are some examples of common light source color temperatures:

1700 K: Match light

1850 K: Candles

2800 K: Common color temperature of tungsten lamp (incandescent lamp)

3000 K: Common color temperature of halogen lamps and yellow fluorescent lamps

3350 K: studio "CP" lights

3400 K: studio lamps, camera floodlights (not flash lights)

4100 K: Moonlight, light yellow fluorescent lamp

5000 K: Daylight

5500 K: Average daylight, electronic flash (varies by manufacturer)

5770 K: effective solar temperature

6420 K: Xenon arc lamp

6500 K: The color temperature of the most common white fluorescent lamp

Warm color light, neutral color light, cold color light have different effects on people.
The color temperature of warm light is below 3300 K, which is similar to that of incandescent lamp. The color temperature of warm light around 2000K is similar to candlelight, with more red light components, which can give people a warm, healthy, comfortable and sleepy feeling. It is suitable for families, residences, dormitories, hotels and other places or places with relatively low temperature; It is better to adjust the light source to warm color light some time before going to bed. The lower the color temperature, the more can maintain the secretion of melatonin.

The color temperature of neuter color light is between 3300 K and 5000 K, neuter color is downy as a result of the light, make people feel happy, comfortable, serene. It is suitable for shops, hospitals, offices, restaurants, waiting rooms and other places.

The color temperature of cool light is above 5000 K, and the light source is close to natural light, which makes people concentrate and not easy to fall asleep. It is suitable for offices, conference rooms, classrooms, drawing rooms, design rooms, library reading rooms, exhibition windows and other places; Using cool light for a period of time before bed can increase difficulty in falling asleep and risk of illness.

We have an in-ground light factory in China, with mature production lines, which can control the color temperature of products and ensure the quality of products. Our R & D team has more than 20 years of experience in outdoor lighting. Customers can fully trust our professionalism, welcome to contact us at any time.
