WebSep 24, 2024 · There are also some light bulbs that contain a ballast within the light bulb. Fluorescent technology changed in the 1990s to include compact fluorescent bulbs (CFLs). They are more energy efficient and were created to replace incandescent light bulbs. Just like incandescent light bulbs, they screw into the socket and you have light. WebThe current that is now flowing into the fluorescent tube causes filaments at each end of the fluorescent tube to heat up and begin to emit electrons into the gas that exists inside the fluorescent tube by a process known as thermionic emission.
