Notes:

1. The dominant wavelength λD is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.

2. θ1/2 is the off-axis angle at which luminous intensity is half of the axial luminous intensity, i.e. Iv(θ1/2)=Iv(0).

3. Tolerance of typical view angle 2θ1/2 is ± 5º.
