What is inside a fluorescent light bulb?
There are two main parts inside a fluorescent light bulb: a tube (also called the bulb) containing argon and mercury vapor, and electrodes at both ends of the fluorescent tube. The inside of the bulb is also coated with a substance called phosphor.OperationA fluorescent bulb does not work like an incandescent bulb. There is no filament such as seen in a regular or incandescent bulb. Instead, electrons flow from one electrode to the electrode at the other end of the tube and bump into the mercury atoms inside the bulb.FunctionWhen the electrons hit the mercury atoms, the atoms release ultraviolet photons of light. These ultraviolet photons, in turn, crash into the phosphor coating inside the bulb, and it is this phosphor that emits the luminescence (light).SignificanceA 15-watt fluorescent bulb shines the same amount of light as a 60-watt regular bulb.BenefitsFluorescent light bulbs consume about two-thirds less energy than incandescent bulbs. They also generate 70 percent less heat, so
