Note : 1. Luminous intensity is measured with a light sensor and filter combination that approximates the
CIE eye-response curve.
2. Iv classification code is marked on each packing bag.
3. The chromaticity coordinates (x, y) is derived from the 1931 CIE chromaticity diagram.
4. Caution in ESD:
Static Electricity and surge damages the LED. It is recommend to use a wrist band or anti-electrostatic
glove when handling the LED. All devices, equipment and machinery must be properly grounded.
5. Tester
PR704 is for the chromaticity coordinates (x, y).
EG&G is for Iv
6. The chromaticity coordinates (x, y) guarantee should be added ± 0.01 tolerance.
