A compact fluorescent lamp (CFL), also known as a compact fluorescent light bulb is a type of fluorescent lamp designed to replace an incandescent lamp. Many CFLs can fit in the existing incandescent light fixtures.
Compared to incandescent lamps of the same luminous flux, CFLs use less energy and have a longer rated life. In the United States, a CFL can save over US$30 in electricity costs over the lampÕs lifetime compared to an incandescent lamp and save 2000 times their own weight in greenhouse gases[
