Note：

    • Luminous intensity is measured with a light sensor and filter combination that approximates the CIE eye-response curve.
    • θ1/2 is the off-axis angle at which the luminous intensity is half the? axial luminous intensity.
    • The dominate wavelength (λd)is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.
