Lamp inrush current
WebbHowever, it must be noted that incandescent lamps have a significant inrush current too! For the first half-cycle, it will (typically) be around 12 times the normal operating current. The iron cored transformer of old for halogen lighting has given way to an electronic equivalent, which may be more efficient, but will never last as long. Webb22 okt. 2013 · Inrush currents at voltage starting angles from 0 to 170 degrees in steps of 10 degrees. The worst case inrush current is, for (led) lamps, most often the one that comes when the voltage starting angle is at 90 degrees. OliNo reports in its measurement report at what starting angle the worst case inrush current has been measured.
