FEATURES

• Wide Viewing Angle

• Deep Red Color

DOUBLE HETEROJUNCTION AIGaAs

HIGH INTENSITY RED LED LAMPS

DESCRIPTION

Exceptional light output

typifies these devices and

provides for their use over a

broad range of drive currents.

The LED material is based on double

heterojunction (DH) AIGaAs/GaAs

technology.
