Editing Fluorescent lamp (section)

===Dimming===
Fluorescent light fixtures cannot be connected to [[dimmer]] switches intended for incandescent lamps. Two effects are responsible for this: the waveform of the voltage emitted by a standard phase-control dimmer interacts badly with many ballasts, and it becomes difficult to sustain an arc in the fluorescent tube at low power levels. Dimming installations require a compatible [[dimming ballast]]. Some models of [[compact fluorescent lamp]]s can be dimmed; in the United States, such lamps are identified as complying with UL standard 1993.<ref>{{cite web|url=https://www.nema.org/Standards/ComplimentaryDocuments/Frequently-Asked-Questions-Regarding-CFLs-and-Dimming.pdf|title=Frequently Asked Questions Regarding CFLs and Dimming|website=www.nema.org|access-date=2020-03-18 |archive-date=2014-05-13 |archive-url=https://web.archive.org/web/20140513210531/http://www.nema.org/Standards/ComplimentaryDocuments/Frequently-Asked-Questions-Regarding-CFLs-and-Dimming.pdf|url-status=live}}</ref>
