Correlated color temperature, measured in kelvins, describes whether a white light appears warmer or cooler. It is a visual description, not a measure of brightness or quality.
Warm light
Values around 2700 K often suit relaxed living spaces and bedrooms. Warm light can support a calm atmosphere and usually coordinates well with timber and warm finishes.
Neutral light
Values around 3000–3500 K can feel crisp without appearing strongly cool. They are often useful where a room combines relaxation and practical tasks.
Cooler light
Values around 4000 K and above can increase the impression of clarity, but should be evaluated for comfort, glare and consistency with adjacent spaces.
Make the plan coherent
Choose temperature by activity, material palette and time of use. Compare physical samples in the room rather than relying only on photographs or packaging.
