This allows the lamp to be driven from a 5 volt/12 volt source without an external current limiter. The red LEDs are made from GaAsP on a GaAs substrate. The High Efficiency Red and Yellow devices use GaAsP on a GaP substrate. The green devices use GaP on a GaP substrate. The diffused lamps provide a wide off-axis viewing angle. The T-13/4 lamps are provided with sturdy leads suitable for wire wrap applications. The T-13/4 lamps may be front panel mounted by using the HLMP-0103 clip and ring. Package Dimensions Figure A.
