NOTE: 1. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE
eye-response curve.
θ
2. 1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
λ
3. The dominant wavelength,
d is derived from the CIE chromaticity diagram and represents the single
wavelength which defines the color of the device.
4. Forward Voltage Tolerance is +/- 0.1 volt.
