can be approximated as a resistor and the lamp (power) factor approaches unity. ere is no ickering
eect and the stroboscopic eect in the light output and the light lumen can be improved. However, the
operation of high-pressure HID lamps with high-frequency current waveforms is oset by the occurrence
of standing pressure waves (acoustic resonance). is acoustic resonance can lead to changes in arc posi-
tion and light color or to unstable arcs. Instability in the arcs could sometimes cause the arcs to extinguish.
e common explanation for acoustic resonance is that the periodic power input from the modulated ...
