I’ve heard that CFLis switch on and off 50 times per second. Can they cause medical problems such as epileptic-type fits, mental disturbances?
CFLis give a constant, flicker free, non-stroboscopic light. They operate at high frequency through their electronic controller at between 30,000-50,000 hertz (normal mains voltage cycles at just 50 hertz or cycles per second). A small number of cases have been reported by people who suffer from reactions to certain types of linear fluorescent lamps. In the majority of these cases, the lamps in question were used in offices, restaurants (in certain European countries) and in limited places in domestic households (such as kitchens and garages) and were almost certainly triggered by OLD technology which operated on a conventional (Copper-Iron) ballasts with a low frequency (<50Hz mains frequency); this is not the case with new energy efficient linear fluorescent lamp technology which unlike earlier energy efficiency technologies, operates on high frequency drivers (for example, certain fluorescent lamps operate on 50kHz or 50,000Hz). The above health related problems can be therefore be
