Notes:
1. Luminous Intensity Measurement allowance is ± 10%.
2. θ_1/2 is the off-axis angle at which the luminous intensity is half the axial luminous
intensity.
3. The dominant wavelength (λd) is derived from the CIE chromaticity diagram and
represents the single wavelength which defines the color of the device.
