Description

This device has been redesigned in 1998 replacing
SiC by GaN technology to meet the increasing
demand for high efficiency blue LEDs.
It is housed in a 3 mm tinted diffused plastic package.
All LEDs are categorized in luminous intensity groups.
That allows users to assemble LEDs with uniform
appearance.
