White light is a combination of all colors in the visible spectrum. The color temperature is measured in degrees Kelvin (K). It refers to how warm or cool something appears when lit by that source, i.e., candles are around 1800-2000 K while sunlight on an overcast day might be as low as 4000 K and regular light bulbs around 2700 K.
The color temperature is the measure of color that indicates how warm or cold a light source appears. The higher the number, the warmer it will appear; conversely, lower numbers indicate cooler lighting which might seem more blue in tone.
When choosing your bulb, manufacturers tend to match these descriptions of white light with temperature:
We created a test video to show you the difference between the light from a soft white 2700K downlight and a warm white 3000K downlight. You can really see the difference between the goldy tones of the soft white against the slightly cooler warm white.
The brightness of all light can be measured by lumens. Be sure to check out the light output of your bulb choice to ensure it’s not too bright or indeed will create enough of the light you’ll need in your choice of lighting product.
Forget watts as a measurement of warm white light or soft white light output when using LED as your lighting source as it only shows how much energy you’ll be using, not how much light you will see as has been the assumption up until recent times.

If your home or office has been using soft white, then warm whites would be a great way to give it a new look and feel. It is the opposite if you have been using warm white light bulbs in your home or office, but now want something with a more traditional design.
