1. A fluorescent lamp, for removable mounting in electrode sockets of a fixture for providing power to the fluorescent lamp, comprising:
a glass bulb that is in a shape of a tube and has a discharge space therein;
external electrodes that are conductive layers each of which covers an outer surface of the glass bulb at an end; and
cylindrical or cap-shaped metal members that are permanently mounted on and connected to the external electrodes to cover at least part of the external electrodes and configured to permit removable electrical connections to the electrode sockets, wherein the metal members are formed such that ends of each metal member recede from ends of each corresponding external electrode toward a center of each corresponding external electrode.
