NOTE:

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

eye-response curve.

3. Iv classification code is marked on each packing bag.

4. The dominant wavelength, λd is derived from the CIE chromaticity diagram and represents the single

wavelength which defines the color of the device.
