A lamp base inner shell including a washer-like base having a cylindrically wall attached at a first end to an outer periphery of the base. The cylindrical wall includes a threaded portion and a plurality of cut-out portions in a second end thereof which define an equal number of tabs, each tab having an indentation extending inwardly. At least one cut-out portion extends to the inner shell base. The inner shell is used to electrically connect and secure a lamp base shell to a lamp tube. The inner shell facilitates automated production of high intensity arc discharge lamps.
