PL 18 Watt 4 Pin 2G11 CFL Lamp

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.
