Question

give two advantages and disadvantage of cfls​

Answer 1

Answer:

Advantages of CFLs

You hear about how great CFLs are, but one reason stands out: energy efficiency.

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. CFLs use 50- to 80-percent less energy than incandescent lights.

While initially they cost more, CFLs are less expensive in the long run because they last much longer than incandescent bulbs. 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. You will see a noticeable change in your electricity bills once you change over to CFLs.

Disadvantages of CFLs

CFLs also have their share of disadvantages and limitations. Most of them stem from the fact that not every bulb is suitable for every job, so it is more a matter of finding the right match. The only serious disadvantage is the mercury content in CFLs.
