Note:

1) Driving the LED in reverse direction is suitable for short term application

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 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 wavelength groups are

measured and binned, single wavelength groups will be shipped on

any one reel.

In order to ensure availability, single wavelength groups will not be

orderable.
