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:CAS140B is for the chromaticity coordinates (x, y) and Iv.

6. The chromaticity coordinates (x, y) guarantee should be added ± 0.01 tolerance

7. Reverse voltage is only for IR test. It can not continue to operate at this situation.
