Compact Fluorescent Lights
Compact fluorescent lights (CFL) are fluorescent lights with a tube diameter of 16mm or less. CFLs are designed to screw into the standard incandescent light bulb socket found in most luminaires. Since fluorescent lights are much more efficient than standard lightbulbs, these compact versions are a great way to get long lasting, cheap and energy-efficient light.
