Notes:
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. Radiant intensity, Ie, in watts/steradian, may be found from the equation Ie = Iv/ηv, where Iv is the luminous intensity in candelas and ηv
is the luminous efficacy in lumens/watt.
4. Please refer to Application Note 1061 for information comparing standard green and emerald green light output degradation.
