NOTE: 1. Luminous intensity is measured with a light sensor and filter combination that approximates
the CIE eye-response curve.
2. θ
1/2
is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
3. Iv classification code is marked on each packing bag.
4. The dominant wavelength, λd is derived from the CIE chromaticity diagram and represents
the single wavelength which defines the color of the device.
5. The Iv guarantee should be added ±30%.
