Abstract
A high pressure discharge lamp having a wire connected to at least one of the electrode assemblies of its arc tube. The wire is formed with two separated legs joined at a common point. The legs are both bent toward the common point. The distance between the legs of the wire contracts and expands to compensate for the expansion and contraction of the lamp's arc tube as the lamp is turned on and off.
