fluorescent tube 
Tube in which the electric current produces ultraviolet radiation converted into visible light by a layer of a fluorescent substance.
Cylindrical metal part that establishes electric contact when inserted into the corresponding outlet.
Long glass cylinder enclosing the components of this type of tube and diffusing light.
End of the tube equipped with two pins that, when inserted into the socket, connect the tube with the electric circuit.
Part in which the lead-in wires are attached.
Glass tube used to empty the air from the bulb and then to fill it with inert gas before it is sealed.
Electric conductor carrying the current to the filament.
The tube is filled with an inert gas under low pressure, with mercury added.
A small amount of vaporized mercury, added to the gas, emits ultraviolet radiation during the electric discharge.
A device placed at each end of the tube; an electric discharge arcs between the two of them.
The tube’s internal coating; it is composed of phosphate particles that convert ultraviolet rays into visible light.
