value for the above rank shall be greater than 0.
* Chromaticity Coordinate Tolerance: ±0.005
* The color rank(sm273d,sm303d,sm353d,sm403d,sm453d) has a chromaticity range within a 3-step MacAdam ellipse.
* The color rank(sm275d,sm305d,sm355d,sm405d,sm455d) has a chromaticity range within a 5-step MacAdam ellipse.
* LEDs from the above ranks will be shipped.
The rank combination ratio per shipment will be decided by Nichia.
