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
