The 20 pages that link to Spectral power distribution, each with the reason it gives.

• WavelengthRelated: It uses wavelength to show where a source’s radiated power lies across the spectrum.

• Visible spectrumRelated: It specifies the wavelength composition of light within and beyond the visible range.

• MetamerismRelated: The full spectral description that metamers deliberately discard in favor of three values.

• Color temperatureRelated: Different spectra can share a color temperature while rendering surfaces differently.

• Light pollutionRelated: A lamp's spectrum affects how strongly it scatters in the atmosphere and affects organisms.

• CIE 1931 color spaceRelated: The observer functions weight this spectrum to calculate its XYZ coordinates.

• Additive colorRelated: It distinguishes physical light mixtures that may appear alike.

• Color rendering indexRelated: A source’s spectrum determines how its illumination shifts the test samples’ colors.

• TrichromacyRelated: Three cone types reduce any such infinite-dimensional function to three numbers.

• Luminous fluxRelated: Photometric weighting is applied across this wavelength-by-wavelength distribution.

• Luminous efficacyRelated: The spectrum is weighted by visual sensitivity before its luminous output is calculated.

• RadiometryBroader topic: It applies radiometric measurement to power resolved by wavelength.

• Color modelCompared with: A spectrum describes physical light, while a color model compresses it into coordinates.

• Correlated color temperatureRelated: Different spectra can yield similar chromaticities and therefore similar CCT values.

• Tristimulus valuesRelated: It supplies the spectral information integrated against color-matching functions.

• CIE standard observerRelated: It is the spectral input weighted by the observer’s color-matching functions.

• Illuminant (colorimetry)Broader topic: An illuminant is a specified SPD; the tables are its entire content.

• Metamerism (color)Related: A metamer is defined by differing reflectance spectra that yield identical tristimulus values.

• Planckian locusRelated: Each temperature supplies a different distribution before chromaticity is calculated.

• Standard illuminantBroader topic: An illuminant is nothing more than an agreed SPD, written as a table of numbers.
