Notes: 1. Luminous intensity is measured with a light sensor and filter combination that approximates the

CIE eye-response curve.

2.

1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.

3. The dominant wavelength,

d is derived from the CIE chromaticity diagram and represents the

single wavelength which defines the color of the device.
