The full form of CFL is Compact Fluorescent Lamp. The CFL bulb is densely packed with a substance called fluorescent. It is also called Energy Saving Light and Compact Fluorescent Tube. CFL bulbs are made from Argon, in which small amounts of mercury are also used. But it takes a little more energy than LED. CFL is an energy saving lamp that consumes less power than the older incandescent lamps. It consists of a glass tube and two electrodes. The glass tube consists of a mixture of argon gas and mercury vapor and has a phosphor coating on its inner surface. By the way, the bulbs which were earlier than CFL are still in use today. They generate more heat when they produce light. And their life is much less than CFL. But the price of CFL is very high but it saves more electricity than its price. CFL holds a lot of importance due to its maximum life and special quality. But if we talk about LED and CFL, then the CFL bulb is slightly lower than the LED.
How does CFL work
CFLs have different mechanisms to produce light than incandescent lamps. In this, in an incandescent lamp, a coil of electric current passes through the filament. It then heats the filament and the filament to produce light. In CFL, current passes through a tube containing a mixture of argon gas and mercury vapor. The current activates the mercury vapor which produces ultraviolet light. The ultraviolet light then excites the phosphor coating inside the tube which produces visible light.
