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 recommended using 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) & IV.
6. The chromaticity coordinates (x, y) guarantee should be added 0.02 tolerance.
