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

response curve.

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.

15% additionary for guaranteed limits.
