Abstract
A metal halide arc discharge lamp includes a metal halide arc tube located within a lamp envelope, a lamp stem having first and second stem leads extending therethrough, and a frame member mechanically connected between the first stem lead and a first end portion of the arc tube. A resistor can be connected between the second stem lead and a starting electrode lead for increased mechanical support. The resistor and the frame member provide the only mechanical support for the arc tube in the lamp envelope. The dome end of the arc tube is mechanically unsupported.
