Notes:1.Luminous intensity is measured with a light sensor and filter combination that approximates the CIE eye-
response curve.
2.
is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
3.The dominant wavelength, d is derived from the CIE chromaticity diagram and represents the single
wavelength which defines the color of the device.
4.I
