The High Efficiency Red source color devices are made with Gallium Arsenide Phosphide on Gallium Phosphide Orange Light Emitting Diode.
The Green source color devices are made with Gallium Phosphide Green 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 ± 0.25(0.01") unless otherwise noted.
3.Lead spacing is measured where the lead emerge package.
4.Specifications are subject to change without notice.
