Note

• Not designed for reverse operation

Note

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

and an accuracy of ± 11 %.

These 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 are 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 reel.

In order to ensure availability, single wavelength groups are not

be orderable

Note

• Wavelengths are tested at a current pulse duration of 25 ms
