It can be applied in the electronic ballast of kinds of fluorescent lamps and electronic energy-saving lamps
No necessity to modify the circuitry
If proper thermistor is parallel connected on the two ends of resonant capacitor of lamps, cold startup of electronic ballast and electronic energy-saving lamps will turn into the preheat startup which can make the preheating time reach 0.4-2s and extend the life of service to three times of the primary
