Description
The Green source color devices are made with Gallium
Phosphide Light Emitting Diode.
The High Efficiency Red source color devices are made
with Gallium Arsenide Phosphide on Gallium Phosphide
Orange Light Emitting Diode.
The Yellow source color devices are made with Gallium
Arsenide Phosphide on Gallium Phosphide Yellow Light
Emitting Diode.
Notes:
1. All dimensions are in millimeters (inches).
2. Tolerance is
±
1") unless otherwise noted.
3. Lead spacing is measured where the lead emer-
ge package.
4. Specifications are subjected to change without notice.
