    Patent number: 7898179
    Abstract: A lamp (100) comprises an outer envelope (120) having first and second electrical lead-ins (140, 160) sealed into a base (180) of the envelope (120). A ceramic arc tube (200) is operatively mounted within the envelope (120), the arc tube (200) having at least one electrode (220) therein. A tubular, niobium feed-through (240) is connected to the at least one electrode (220) and sealed to the ceramic body (120) at a joint (260) that can comprise a glass frit (260a). A stainless steel rod (280) is electrically connected between the electrical lead-in (140) and the tubular niobium feed-through (240), the stainless steel rod (280) being the only electrical connection between the lead-in (140) and the niobium feed-through (240).
