Notes:

1. Luminous Intensity Measurement allowance is ± 10%.

2. θ_1/2is 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.
