The 15,000 K black-body spectrum (dashed line) matches the visible part of the stellar SPD much better than the black body of 9500 K. All spectra are normalized to intersect at 555 nanometers. In astronomy , the color temperature is defined by the local slope of the SPD at a given wavelength, or, in practice, a wavelength range.
The spectrum of a standard illuminant, like any other profile of light, can be converted into tristimulus values. The set of three tristimulus coordinates of an illuminant is called a white point . If the profile is normalized , then the white point can equivalently be expressed as a pair of chromaticity coordinates .
Single color, non-addressable: Every LED on the strand is a single white colour, typically ranging from 2200K to 6500K in color temperature, or any of several monochrome colors covering the range of the visible spectrum (generally from 400-700 nanometers in wavelength).

The new box, called XUMO, replaces the old set-top cable box and has several new features. Spectrum cable introduces a new souped-up ‘cable box.’ What it does, how much it costs
Blacksmiths work iron when it is hot enough to emit plainly visible thermal radiation. The color of a star is determined by its temperature, according to Wien's law. In the constellation of Orion, one can compare Betelgeuse (T ≈ 3800 K, upper left), Rigel (T = 12100 K, bottom right), Bellatrix (T = 22000 K, upper right), and Mintaka (T = 31800 K, rightmost of the 3 "belt stars" in the middle).
