CFL stands for Compact Fluorescent Lamp. It is an energy-saving bulb that consumes lesser energy as compared to conventional incandescent lamps. It has two electrodes and a glass tube that contains a mixture of argon gas and mercury vapour. The inner surface of the tube has a filling of phosphorus.
A brief history of CFL
- CFL, produced in 1890 by Peter Cooper Hewitt is a part of the generation of Electric Lamp.
- It got redesigned in 1939 in order to make it cheaper.
- It received another update in 1976 making it cheaper than before.
Working principle of CFL
CFL has multiple illumination generating pathways. The electric current travels via a wire filament in bright light and heats the thread to create light. The current transfers with the help of the tube that contains argon gas & mercury vapour and activates the mercury vapour further generating UV light.
Types of CFL
There are two types of CFL:
1. Integrated: This type consists of electronic ballast, bayonet fitting, and tube.
2. Non-Integrated: This type consists of a permanently fixed electronic ballast in the luminaire which is not one with the bulb. Thus, when expired only the bulb needs to be changed.
Advantages of CFL

- Long-lasting.
- Cheap.
- Reduces CO2 emissions.
- Versatile and highly efficient as it comes in various sizes, shapes, and capacities.
- Convenient to use and we can use it in various light fixtures like ceiling lamps, table lamps, dimmer lamps, etc.
- Generates less heat.
