Before LED and energy-saving bulbs, filament lamps were used in home lighting. The filament bulbs only had lights in the 2700-3000K range. Therefore, the concept of Kelvin was not known among the people. Became known with the use of energy-saving light bulbs and LEDs in daily life. Continue reading our blog post that we have prepared for you to find the answer to the question of what is Kelvin.
What is Kelvin?
Kelvin is a concept that expresses the color temperature of light. The Kelvin scale is an absolute thermodynamic temperature scale, meaning it uses absolute zero as its null point. The history of the Kelvin concept dates back to the middle of the 19th century. The kelvin, symbol K, is the SI base unit of temperature, named after the based engineer and physicist William Thomson, 1st Baron Kelvin.
Lighting products produced today have different color temperatures. So we have many variations of color temperatures. This gives the opportunity to use different color temperatures in different places. Different color temperatures can be used in outdoor lighting, and different color temperatures can be used in indoor lighting. For example, the color of daylight can be used in homes and bright colors can be used in gardens. Detailed information about color temperatures is listed below.
Warm Light (2700K-3200K)
The range of 2700-3200K is within the scope of warm light. Warm light creates a comfortable atmosphere in the environment where it emits light. It is suitable to be used indoors.
The range of 4000-5000K is within the scope of daylight. It is frequently used in working environments because daylight is energizing and spacious.
Cold Light (5500- 6500K)
The range of 5500-6500K is within the scope of cold light. It is generally preferred in places such as gyms and jewelry stores.
