An electric current in the gas excites mercury vapor which produces short wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow a fluorescent lamp converts electrical energy into useful light much more efficiently.
Fluorescent light dimensions.
There are three common sizes shown in the chart the below.

Lamps are typically identified by a code such as fxxty where f is for fluorescent the first number xx indicates either the power in watts or length in inches the t indicates that the shape of the bulb is tubular and the last number y is the diameter in eighths of an inch sometimes in millimeters rounded up to the nearest millimeter.
