Notes:
1.
Luminous intensity is measured with a light sensor and filter combination that approximates the CIE
eye-response curve.
2.
3.
θ
1/2
is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
The dominant wavelength,
λ
d
is derived from the CIE chromaticity diagram and represents the single
wavelength which defines the color of the device. Peak Emission Wavelength Tolerance is +/- 1nm.
4.
5.
Forward Voltage Tolerance is +/- 0.1 volt.
Reverse voltage (VR) condition is applied to IR test only. The device is not designed for reverse operation.
