Notes: 1. Luminous intensity is measured with a light sensor and filter combination that approximates the
CIE eye-response curve.

3. The dominant wavelength,
single wavelength which defines the color of the device.
1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
