A lamp assembly for a substrate processing chamber is described. The lamp
assembly comprises a tubular body having first and second ends, a lamp
element at least partially seated in the first end having a filament and
first electrical connectors, transmission wires attached to the first
electrical connectors, and a rigid plug flexibly positioned relative to
the second end of the tubular body having second electrical connectors
attached to the transmission wires. The flexibly positioned rigid plug is
generally capable of a range movement in directions both perpendicular
and parallel to a longitudinal axis of the tubular body. In one version,
the rigid plug comprises first and second plug elements.
