Compact Fluorescent Lamps (CFLs) are energy-saving light bulbs, which last longer and use far less energy than traditional (or incandescent) light bulbs for the same level of light intensity.
CFL Lamps are a twist on traditional fluorescent technology. Created as a more energy-efficient option for conventional incandescent applications, CFLs screw into a medium base socket and utilize a spiral design – as opposed to a long tube – making it “compact.” Many CFLs also have an integrated ballast, unlike traditional fluorescent tubes.
The most common reason people use compact fluorescent bulbs is to save energy.
You probably don’t want to use a CFL bulb in the vintage chandelier hanging above your dining room table. However, there are some other applications for these lamps that you see quite often.
