Abstract
A method of forming a metal halide discharge tube comprises: arranging a tubular body () in an essentially vertical orientation; disposing a loose-fit T-plug () having a cylindrical portion () and an annular flange () in an upper open end of the tubular body () so that the cylindrical portion () of the T-plug () is disposed within the open end of the tubular body () in a contact-free, spaced relationship with an inner wall of the tubular body and with the annular flange () seating against an annular top end edge surface () of the tubular body (); and firing the tubular body and the loose-fit T-plug to shrink fit the tubular body and the loose-fit T-plug to interfuse the loose-fit T-plug with the upper end of the tubular body in a manner which results in a unitary/monolithic body.
