CFL is an alamative to electric bulbs for effective running of school.
Option (2)
Explanation:
- The CFL means Compact Fluorescent Lamp. This is the energy saving lamp in replacement of the normal lamp.
- In the CFL lamp the electric current is passed through the tube which contained argon and some of the mercury vapour.
- This tube creates the invisible ultraviolet rays to excite the fluorescent coating inside the tube and then the light initiated. Only one disadvantage of the CFL light is that this is costly to purchase in comparison with the normal bulb.
