6.1 General Attributes

Abbreviation Full Name
CCT Correlated Color Temperature

The color radiated by a black-body radiator under different temperatures.
CCT has the color that is the closest to the ideal black-body radiator.
CRI (Ra)
Color Rendering Index

The average value of R1 ~ R8, where R1 ~ R8 represent the value of eight
standard colors as defined by Commission International de l'Eclairage (CIE).
A CRI value of 100 indicates the best quality of light for rendering color
appearance, while a value of 0 indicates the worst quality of light for
rendering color appearance.
R1, R2, ... , R15 Color Rendering Index Varieties
Represents the quality of the light source with the indexes corresponding to
15 standard colors, including: R1: light grey-red; R2: dark grey-yellow; R3:
saturated yellow-green; R4: middle yellow-green; R5: light yellow-green; R6:
light blue; R7: light purple-blue; R8: light red-purple; R9: saturated red; R10:
saturated yellow; R11: saturated green; R12: saturated blue; R13: white skin
color; R14: leaf green; and R15: yellow skin color.
Lux
 Illuminance
Light flux received by each unit area.
λp
 Peak Wavelength
Wavelength with the highest intensity in the measured spectrum.
λpV
 Peak Wavelength Value
Intensity of the peak wavelength in the measured spectrum.
λd Dominant Wavelength

Used to express the color of the measured light. May be hybridized by the
spectrum color of the wavelength and the standard illuminant E(x, y = 0.333,
0.333).
I-Time Integration Time
Integration time measured by the spectrometer.
x, y CIE1931 Chromaticity Chart Color Coordinates
Light color with 2-dimensional plane coordinates (x, y) as defined in CIE
Chromaticity Chart CIE1931.
u',v' CIE1976 Color Coordinate
