LED color temperature is a way to describe the light appearance and it is measured using the Kelvin scale represented by numbers followed by a “K”. Manufacturers and retailers can differ in their definition of the light range titles.
The Kelvin scale is a measure of the color temperature of light sources, including LED lights. It is based on the principle that as an object is heated, it emits light at different wavelengths, which correspond to different colors. The Kelvin scale is used to describe the perceived color of light emitted by a source, with lower values corresponding to warmer, more yellowish light, and higher values corresponding to cooler, bluish light.
For LED lights, the Kelvin scale is commonly used to describe the color of the light emitted, with values ranging from 2700K to 6500K or higher. Lower Kelvin values (2700K-3000K) correspond to warm white light, which is similar in color to incandescent bulbs and is often used in residential and hospitality settings to create a cozy and inviting atmosphere. Kelvin values in the range of 3500K-4500K are considered neutral white, while higher Kelvin values (5000K and above) correspond to cool white or daylight color temperatures, which are often used in commercial and industrial settings where higher levels of brightness and visual acuity are required.
The color temperature of light bulbs (lamps) is meant to replicate the Kelvin temperature of heat up a metal object.
It is important to note that the Kelvin scale is only one factor to consider when selecting LED lights, and other factors such as color rendering index (CRI) and luminous efficacy should also be taken into account to ensure that the light source is appropriate for the intended application.
