DESCRIPTION
The VLMW71.. is one of the most robust and light
efficient LEDs in the market. With its extremely high
level of brightness and the ultra low high profile, which
is only 1.5 mm are highly suitable for both conventional
lighting and specialized application such as
automotive signal lights, traffic lights, channel lights,
tube lights and garden lights among others.
PRODUCT GROUP AND PACKAGE DATA

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 in any one reel.
In order to ensure availability, single wavelength groups will not be orderable.
