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

CIE eye-response curve.

2. θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.

3. The dominant wavelength, λd is derived from the CIE chromaticity diagram and represents the

single wavelength which defines the color of the device.
