VLWW960.

Note:

Luminous flux is tested at a current pulse duration of 25 ms and an accuracy of ± 11 %.

The above type numbers represent the order grous which include only a few brightness groups. Only one group will be shipped in one tube (there

will be no mixing of two groups on each tube).

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 in any one tube.

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