Question

What are the advantages of fluorescent lamps over incandescent lamps.

Answer 1

Hint:: In fluorescent lamps, fluorescence is used to generate light when mercury vapor inside the lamp is excited by electric current flow. Whereas in incandescent lamps, the bulb's filament is heated by supplying electricity as a result of which bulb glows.

Complete step by step answer:
We can understand the advantages of fluorescent lamps over incandescent lamps in a step by step manner, as mentioned below:

1. Fluorescent lamps can produce the same amount of light as incandescent lamps with lesser energy input, which means that they are more efficient than incandescent lamps.
2. The life of fluorescent lamps is 10 to 15 times longer than the incandescent lamps, so we can use them for a longer time, resulting in a reduction of maintenance and replacement cost if used with a vehicle.
3. The distribution and diffusion of light obtained in fluorescent lamps are much better than those obtained in incandescent lamps.
4. As we know, the incandescent lamp's filament glows by transforming electrical energy to heat energy, which means that the emission of energy is high. In the case of fluorescent lamps, the light the current is required to excite the vapor of mercury, resulting in lesser emission of energy.

Note:The initial cost of fluorescent lamps is higher because of the complexity involved in its manufacturing. The main disadvantage of fluorescent lamps is the chemical used in them can pollute the environment if it is leaked, even if it is harmful for the health of living animals.
