ABSTRACT:
A lamp having a ceramic arc envelope, an end structure coupled to the ceramic arc envelope and extending across an opening in the ceramic arc envelope, where the end structure comprises a passageway communicative with an interior chamber of the ceramic arc envelope is provided. The lamp further includes a molybdenum-rhenium electrode lead extending through and sealed with the passageway. The molybdenum-rhenium electrode lead includes a molybdenum-rhenium alloy. Furthermore, the lamp includes an arc electrode tip coupled to the electrode lead inside the interior chamber.
