S I G N & D I G I T A L G R A P H I C S • September 2018 • 25 While LED lighting does not perfectly match the output of this piece of metal, we use the CCT convention to describe the appearance of light as it relates to this type of black body radiator. The sun is an ideal black body radiator and above atmo- sphere has a CCT of about 5900K. Depending upon the time of day and conditions, the CCT we see varies between 5000K at horizon daylight to 6500K during overcast conditions. In general lighting, warmer CCTs that mimic candlelight are used to create relaxation, and cooler CCTs are used to enhance concentration in office environments (see Figure 1).
