1. A semiconductor light source, comprising:
- an electrically and thermally conductive outer lead frame having;
a first end having a plurality of facets spaced about an outer surface of the outer lead frame;
a second end spaced from the first end and configured for mating with an electrical socket;
a hollow passageway extending through the outer lead frame from the first end to the second end;
an electrically conductive inner lead frame having;
a shaft having a first end and a second end spaced from the first end, the shaft extending through the passageway of the outer lead frame,a cap attached to the first end of the shaft;
an insulation layer electrically isolating the inner and outer lead frames; and
a semiconducting LED positioned on at least one of the plurality of facets and in electrical communication between the cap and the outer lead frame.
