Posted By allan wood hi everybody, has any one out there come across a situation where 110v fluorescent lighting has caused the stroboscopic effect with work equipment such as a circular saw. i am trying to convince site managers to select a different type of light fitting for such instances, but they want hard evidence. i have looked at the cibse publications and it states that it is rare with modern lighting but can still happen,can any of you add to this. thanks in advance

Posted By Jack It's a long time since I've come across this! It should be eliminated in modern designs (electronic ballasts, operating at 20kHz or by connecting adjacent fixtures to different phases or even by tube coatings (?)). If it's an existing installation does it cause a problem? If you are about to instal the lighting suggest you ask the supplier how the strobe effect will be eliminated.
