What is color temperature?

Regarding white LED lights, we often talk about warm white and cool white. This is how we feel about these two kinds of white light led strip. But in fact, there is a special expression for the white light called kelvin color temperature. 

Kelvin color temperature refers to the color change of a standard black body* after being heated (*The standard black body does not exist, it is just an ideal object).

As the kelvin color temperature rises, the standard black body slowly changes to red, orange, yellow, white, and then to blue. Kelvin color temperature shows the light color change when the black body is heated from a 1000K color temperature to a 10,000K color temperature. 

To put it simply, a black body is heated to a 2700 Kelvin color temperature and will appear orange, so 2700K color temperature represents an orange color. 

•  2700K-3000K, Warm white, a warm white/yellow glow (candlelight hues) •  4000K-4500K, Natural white, a bright white glow •  6000K-6500K, Daylight white, a crisp daylight glow (white hues) •  Above 7000K, Cool white, a cold glow (bluish hues)

Although 3000K LED light is similar to 2700K light, their actual suitable locations are not always the same. 3000K LED strip lights are brighter and more suitable for kitchens, bathrooms, and laundry rooms.

4000K light like moonlight, less yellow and whiter than 3000K, belongs to neutral white, and is a crisp lighting. Requires more precision for lighting objects, 4000K light strips are more suitable for you than 3000K. 

6000K LED light is similar to a cloudy sky, and is commonly found in various display cabinets or office areas. The 6000K lighting installed in the jewelry display cabinet can display the beauty of the jewelry without any dead ends. At work, 6000K LED light is refreshing and helpful to work enthusiasm.

 

►Warm White VS Cool White
