Question

Which of the following is more energy efficient?
a) Incandescent Bulb b) Fluorescent Tube light c) CFL d) None of these

Answer 1

According to me the answer will be (b) Fluorescent Tube light.

Answer 2

c) CFL. CFL is more energy efficient than incandescent bulb or fluorescent tube light.

Explanation:

The most energy-efficient alternative available is a Compact Fluorescent Lamp (CFL). Often referred to as an energy-saving light or compact fluorescent tube, a compact fluorescent lamp is made to replace incandescent light bulbs.

Some models are compatible with light fixtures made to accommodate incandescent bulbs. CFLs have an efficiency that is up to four times greater than that of incandescent or fluorescent tube lighting.

A 100-watt incandescent bulb can be swapped out for a 22-watt CFL to produce the same amount of light. CFLs use between 50 and 80 percent less energy than incandescent bulbs.

Although CFLs initially cost more, they end up saving you money since they last so much longer than incandescent lights.
