At the lower end of the scale from 2000K to 3000K the light produced is called warm white and ranges from orange to yellow-white in appearance.
5000 kelvin color. A so-called black body which in theory swallows all light is first heated until it glows red. Then moving up to around 5000-6000 scale you get to the white-hot zone. The color temperature of Kelvin will not tell you how anything about the brightness of a light source.
Kelvin is not a measure of brightness rather it is a measure of color temperature. On the low end of the scale you have 1000-2000 Kelvin. This is also the case for determining the color temperature.
You likely will see that 5000K appears. The Kelvin color temperature does not depend on brightness. This color is 100 neutral and does not contain yellow or blue tint.
Color temperature CCT defined in simple words is the measurement used to characterize a white light that emitted and measured in kelvins. That is 100 backwards. Gives off a bright bluish hue of light often found in commercial locations.
Above 5000K color temperature The color temperature blue light above 5000K is very obvious which is why we do not recommend reading in the sun. As for how close or far from your plants should you please your grow lights I usually recommend about 6 to 8-inch. It is a measure used to find the quantity of light used for viewing in Kelvin scale K.
Kelvin ranges between 5000 looks pure white and 6500 has a slightly blue tint are most like sunlight. Color temperatures between 3100K and 4500K are referred to as cool white or bright white. Click to see full answer.
