A fluorescent lamp or a fluorescent tube is a low pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. 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 bulb to glow.
A 5-watt, 25-watt, or 300-watt incandescent bulb can be screwed into an Edison socket and they will all work as they are supposed to. One socket; any wattage. That is not true of fluorescent lamps, because the lamp must match the ballast in the fixture.different lengths are associated with different wattages; for example, 4-foot bulbs were 40-watts (at one time).hapes, sizes and bases. The most common form of fluorescent lamp is a straight tube. The diameter of the tube is described in eighths of an inch, as it is for incandescent lamps, so a fluorescent lamp 1 inch in diameter (eight eighths) is a T8.
