Notes:1.Luminous intensity is measured with a light sensor and filter combination that approximates the CIE eyeresponse 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. 4.I V needs 15% additionary for guaranteed limits.
