Part of the significance of Osram's latest laboratory result is the specific color of the light produced by the LED. A higher color-correlated temperature corresponds to a greater blue component in the spectrum and a lower red component. An incandescent lamp with a warm white light, for example, has a CCT of 2700 K, whereas a daylight fluorescent lamp has a color temperature of 6000 K. Historically, it has been much more difficult to produce warm-white LED emission with a high efficacy, because the emission tends to be dominated by the blue emission of the LED chip.
