What is Color Temperature? | How to Read Kelvin (K) and Choose by Room

When choosing lighting, you'll often see numbers like "3000K" and "5000K." This is "color temperature" (色温), a unit that represents the color of light.

Understanding color temperature makes it easier to choose the right light for your room and scene.

Kelvin (K) is the unit for light "color"

The smaller the Kelvin number, the warmer the orange light; the larger the number, the clearer and bluer the light. Incidentally, just as the color of outdoor light changes in the morning, afternoon, and evening, people live under different colored lights throughout the day.

Representative Color Temperatures and Suitable Scenes

Incandescent color (approx. 3000K): Warm orange. For relaxing in the living room, in the bedroom, or for a calm dining atmosphere.
Warm white (approx. 3500K): Midpoint between incandescent and white. A balanced type for calmness and brightness.
White (approx. 4000K): Clear, natural white. For studying, working, or desk work.
Daylight white (approx. 5000K): Brightness similar to midday sunlight. For reading or detailed tasks where you need to see clearly.

"Switching" rather than "Choosing one"

Even within a single day, the ideal color temperature differs between the daytime, when you want to concentrate, and the nighttime, when you want to relax. A ceiling light with a color tuning function allows you to change the light color according to the time and scene, offering versatile use with one unit.

In the case of lipro

The Sunlight Ceiling Light supports color tuning from 3000K (incandescent color) to 5000K (daylight white). You can switch with a single remote control, from 4000K white in "study mode" when you want to concentrate, to incandescent color when you want to relax.

Summary: Understanding color temperature makes choosing light easier

Knowing the meaning of Kelvin numbers makes it easier to choose the right light for your room and scene. If you're unsure, it's safest to choose one that allows for color adjustment.
