The lower the kelvin of the light the more yellow the light will appear.
Warm lighting vs cool lighting. WARM WHITE Warm white bulbs will have a Kelvin temperature of 2700K. Warm light versus cool light. Whereas warm light simulates ambient sunsets in the 1000 to 5000 Kelvin range cool light is bright and clinical in the 5000 to 10000 Kelvin range.
As part of our natural human circadian rhythm warm light seems to relax us and help us wind down for the day and get ready for sleep. Warm white light bulbs have a color temperature ranging from 2500K up to 3000K. Warm white is a more comfortable white color that is mostly used in living and residential areas.
What is the right temperature for you homeIn todays video Im sharing some of Dr Jason Littleto. Warm White is around 4000K and Cool White can range from 6000K and beyond. Warm lights have lower color temperatures and therefore appear more yellow while cool lights have higher color temperatures and appear whiter or bluer.
Naturally you can create warm and cool light with artificial lighting as well. So - when choosing lights at home dont be scared of LED - its great for energy efficiency and good quality LED lights have amazing colour - better than any technology that has come before. Cool lighting is also a better choice for security lighting as it is not inviting to intruders and is bright and clarifying which should scare them away.
Warm light is yellow and cool light is blue. Cool white and the slightly less harsh Natural White are much lower demand than warm white for domestic. Warm White Warm White and Cool White are measured on the Kelvin scale represented by the letter K.
A sunset is about 4000K and is considered a cool white color. Create the ideal cozy atmosphere with relaxing warm light and focus the attention in active areas with cool light. The glow-from-the-fire lighting is about 2000K and is considered a warm color.
