Note

• Luminous intensity is tested at a current pulse duration of 25 ms

and an accuracy of ± 11 %.



The above type numbers represent the order groups which

include only a few brightness groups. Only one group will be

shipped on each bag (there will be no mixing of two groups on

each bag).



In order to ensure availability, single brightness groups will not

be orderable.



In a similar manner for colors where wavelength groups are

measured and binned, single wavelength groups will be shipped

on any one bag.



In order to ensure availability, single wavelength groups will not

be orderable.
