What is the color temperature of LEDs?
Color temperature is determined by comparing its chromaticitywith a theoretical, heated black-body radiator. Got that? What people really want to know is how does the light from LEDs compared with their perceptions of light from other sources. Since the spectrum of light from a white LED does not have the same form as that of any other light source, the color temperature of LEDs is somewhat subjective. LightBlasters original LEDs had a comparitive color temperature of 5,500K, a blue-white mixture we called cool-cool. We worked with the LED manufacturers to produce a warmer LED, and they provided a blue-yellow variety with a comparitive color temperature of about 3,500K, which we called warm-warm. We mixed these two LEDs into a cool variety (CWC = 2/3s cool-cool and 1/3 warm-warm) and a warm variety (WCW – 1/3 cool-cool and 2/3 warm-warm). More recently, we have found an LED manufacturer that can reliably provide what we call a “natural” color, with a comparitive color temperature of ab
