WebA: Fluorescent bulbs or tubes contain mercury vapor and have a special coating on the inside. When electricity is applied to these bulbs, they emit light, producing around 75% less heat than incandescent bulbs and using much less energy. WebApr 8, 2024 · For new equipment, installers often choose fixtures that come with a ballast to operate the bulbs. Many fluorescent ballasts are now universal voltage, meaning they can be run on line voltage from 120 to …
