Abstract: A single pin base for a fluorescent lamp comprises first and second base members. The first base member includes a shell, a first disk of insulating material secured to or formed from the shell, and a contact member centrally mounted on the disk and adapted to receive the lead-in wire from one end of the fluorescent lamp. The second base member includes a second disk of insulating material and a single contact pin centrally mounted on the second insulating disk. A metal disk is located within and secured to the single contact pin and is provided with an aperture formed therein for receiving the contact member of the first base member and for frictionally engaging the contact member so that the second base member is retained on the first base member.
