NOTES:
1. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE eye-response curve.
2. Luminous intensity rank classified products support two ranks.
3. θ 1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
4. Iv classification code is marked on each packing bag.
5. The dominant wavelength, λd is derived from the CIE chromaticity diagram and represents the single wavelength which
defines the color of the device.
