Notes: | |||||||||||||
l Wave Length and Luminous intensity can be change by customer request. | |||||||||||||
l Luminous intensity data is base on the chip size test result that made from ATECOM’s EPI Wafer,Red Led is base on 12×12mil2,Yellow and Yellow/Green Led are base on 8×8mil2 . The real electronic performance will be fully rely on chip process. |
