Note:
1. θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
2. The dominant wavelength, λd is derived from the CIE chromaticity diagram and represents the single wavelength which
defines the color of the device.
3. Forward Voltage Tolerance is +/- 0.1 volt.
Note: Tolerance on each Intensity bin is +/-11%
