Note: 1. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE
(Commission International De L'Eclairage) eye-response curve.
2.
θ
1/2
is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
3. The dominant wavelength,
λ
d
is derived from the CIE chromaticity diagram and represents the single
wavelength which defines the color of the device.
4. The Iv guarantee should be added
