CCT

CCT is an acronym for Correlated Color Temperature. It defines the control of color temperature (abbreviated as K for Kelvin) and thus describes the color impression of a light source. CCT refers to the temperature of a so-called Planckian radiator, which corresponds to a specific color of light. The lower the Kelvin value, the warmer the light appears.   For lights with a CCT function, the color temperature can be adjusted—usually conveniently via remote control. A daylight curve can also be set, which can be very beneficial given that light colors have a significant effect on our well-being. For example, a cooler or blue-white light can be set during the day, as this lowers the concentration of the hormone melatonin in our blood, making us feel more active and energetic. In the evening, the CCT function can then be used to switch to a warm, dimmed light to enhance coziness and boost the production of the sleep hormone. Depending on the room, it therefore makes sense to use different light colors—such as warmer tones for living rooms or bedrooms, or cooler tones for kitchens or home offices. However, CCT LED lights offer the greatest flexibility, as they allow you to adjust and set the color temperature. Characteristic light colors include, among others: candlelight with a CCT of approximately 1500K; warm white with a CCT below 3300K, found for example in an incandescent bulb; neutral white with a CCT value of 3300K to 5000K, found for example in a fluorescent or xenon lamp; and cool white (daylight white) with a CCT above 5000K—for example, the midday sun
