ABSTRACT:

The lamp base includes a lamp base body and at least one fixed key on the lamp base body. The lamp assembly further includes a movable key on a key carrier that is movable to two or more different positions on the lamp base body during manufacturing. The key carrier is attached to the lamp base body in one of the positions such that the fixed and movable keys provide variable keying of the lamp assembly. The lamp base body and the key carrier may have interengaging ratchet elements for defining discrete positions of the movable key.
