Summary0000787: Mixed white LED_bin grading spec.
DescriptionHi Mr.Yoon and SB,
We have checked the LED circuit for the two PCBAs return from Everlight.
It looks that the input current, resistors and forward voltage of LEDs has no significant defect.
Please check our measurement report as attached file and let us know your comment.

In addition, we would like to know your idea about the criteria of the mixed white LED color of Eagle box.
As per the proposal I provided on 10/15, we need ALT/SKB's confirmation and approval if you are agreed with our CIE bin grading spec.
We got to complete this specification immediately as you know that the Eagle is continuously mass production now
