Editing Stroboscopic effect (section)

==Dangers in workplaces==
Stroboscopic effect may lead to unsafe situations in workplaces with fast moving or rotating machinery. If the frequency of fast rotating machinery or moving parts coincides with the frequency, or multiples of the frequency, of the light modulation, the machinery can appear to be stationary, or to move with another speed, potentially leading to hazardous situations.{{Citation needed |date=August 2023}}

Because of the illusion that the stroboscopic effect can give to moving machinery, it is advised that single-phase lighting is avoided. For example, a factory that is lit from a single-phase supply with basic lighting will have a flicker of 100 or 120&nbsp;Hz (depending on country, 50&nbsp;Hz x 2 in Europe, 60&nbsp;Hz x 2 in US, double the nominal frequency), thus any machinery rotating at multiples of 50 or 60&nbsp;Hz (3000–3600rpm) may appear to not be turning, increasing the risk of injury to an operator. Solutions include deploying the lighting over a full 3-phase supply, or by using high-frequency controllers that drive the lights at safer frequencies<ref>{{Citation | url = http://electrical.theiet.org/wiring-matters/28/complete.cfm | pages = 4 | journal = Wiring Matters | date = Autumn 2008 | issue = 28 | publisher = The IET | title = Section 559 luminaries and lighting installations: An overview | last = Cronshaw | first = Geoff | access-date = 2012-09-20 | archive-date = 2016-12-19 | archive-url = https://web.archive.org/web/20161219213045/http://electrical.theiet.org/wiring-matters/28/complete.cfm | url-status = dead }}</ref> or direct current lighting.{{Citation needed |date=August 2023}}

The 100/120 Hertz stroboscopic effect in commercial lighting may lead to disruptive issues and non-productive results in workspaces such as hospitals & medical facilities, industrial facilities, offices, schools or video conferencing rooms.<ref name="FB:January2025" />
