Question

CFL's are more energy efficient than ordinary bulbs. Explain
​

Answer 1

Answer:

CFLs are up to four times more efficient than incandescent bulbs. You can replace a 100-watt incandescent bulb with a 22-watt CFL and get the same amount of light. ... And since CFLs use a third of the electricity and last up to 10 times as long as incandescent bulbs, they are much less expensive overall.

Answer 2

CFL are more energy efficient than ordinary bulbs because -

• In the ordinary bulbs the electricity is first converted into heat energy and then converted into light energy. This two step conversion process requires a high amount of electricity.

• On the other hand,the CFL bulb produces light energy when the electricity is given into the bulb to produce UV rays (this UV rays produces light rays by exciting the fluorescent layer inside the bulb) by different types of chemical reactions happening inside the tube of CFL bulb. This whole process is a one stage process which requires less amount of electricity than the normal bulbs.
