Single twin 2-pin compact fluorescent lamps (CFLs) are energy-efficient lighting solutions featuring a twin-tube design and a 2-pin base. They are commonly used in various fixtures, including desk lamps, wall sconces, and ceiling lights, providing bright and consistent illumination. 

G23 Base 

CFLs with a G23 base have two pins spaced 23 millimeters apart. They are widely used in residential and commercial lighting applications, offering easy installation and compatibility with a range of fixtures. These lamps are available in various wattages and color temperatures to suit different lighting needs. 

GX23 Base 

CFLs featuring a GX23 base also have two pins but are designed for specific fixtures requiring this base type. They provide similar energy efficiency and illumination quality as G23 base lamps, with compatibility tailored to fixtures designed for the GX23 configuration.
