The Impact of Color Temperature: A Comprehensive Guide to LED Lighting

Natural light is white light which is not static but a dynamic source with changing tone and brightness, as a day goes by and seasons change. The tone of white light is called color temperature and is express in degrees Kelvin (K).

The color temperature of daylight changes during the day, from 2000K at sunrise and sunset to 5500-6500K at noon. In the shade in can even go to 8000-10000K.

Artificial light sources are available with all relevant color temperatures of sunlight. Some of them, such as incandescent lamps, can be produced with only one color temperature: 2700K. LEDs are light sources that can be produced with all color temperatures from 2000K to 10000K, while the most are found in the 2700-6500K range.

Understanding LED Color Consistency: The Crucial Role of Macadam Ellipse Sorting

Macadam Ellipses LED color sorting (3 step, 5 step): Explained

To understand what Macadam Elipse color sorting is, we first have to know about LED color consistency.

LED color consistency has an easy explanation. Everyone can notice when color consistency is poor, especially in the case of white light. The image below shows this clearly, the white LED light has different shades.

Thus, high color consistency means all white LED have the same shade while poor color consistency looks like in the image above. This is the most extreme of cases, with LEDs or luminaries having all the shades of white mixed up: warm white, pure white and cold white in one installation. However, the same phenomenon exists for products marketed as warm white, pure (natural) white or cold white.

White light has different shades

While there is no consensus, warm white light for LEDs has a value of 2500K-4000K on the color temperature scale, pure white 4000K-5000K and cold white 5000K-10.000K.
