09 Jul Kelvin & Correlated Color Temperature
When people think about LEDs, often a visual of harsh blue light comes to mind. However, there is a whole scale (the Kelvin scale to be exact) that measures the color temperature of light ranging from orangey-red (think match flame) to white, and then to blue (think deep blue clear sky). LEDs come in this entire range which is listed as the Correlated Color Temperature or “CCT” which is measured and expressed in degrees Kelvin. The CCT can have a dramatic effect in both mood and function on your environment. Basically, the lower the Kelvin, the warmer the light, and the higher the Kelvin, the whiter or bluer the light.
So which CCT should you purchase?
It depends on the mood and feel you’re trying to create within your environment. Traditional incandescents are known for creating a warm, cozy feel. They typically run from 2700-3000K. So if you’re switching out incandescents for LEDs and want the same light color, purchase LEDs within this same “soft or warm white” range.
Wanting to create a more crisp and energetic feel? Purchase lights within the 4000K and higher range. This range is more conducive for work and learning environments, as well as productivity, since the whiter light color will keep you more alert. Once you hit 6000K and higher, the light will begin to take on a bluish tone.
If you really want to set the mood with a candle-lit vibe, check out our amber coated filaments. These come in Kelvin ranges of 1900K, 2200K, and 2400K.
