Note
• Chromaticity coordinate groups are tested at a current pulse direction of 25 ms and a tolerance of ± 0.01.
Note
• Luminous intensity is tested with an accuracy of ± 15 %.
The above type Numbers represent the order groups which
include only a few brightness groups. Only one group will be
shipped on each reel (there will be no mixing of two groups on
each reel). In order to ensure availability, single brightness
groups will not be orderable.
In a similar manner for colors where color groups are measured
and binned, single color groups will be shipped on any one reel.
In order to ensure availability, single color groups will not be
orderable.
