What is the biggest difference between the electronic ballast of high-voltage sodium and the traditional inductive ballast?

Compared with inductive ballast, electronic ballast has the following advantages: the power factor of electronic ballast is higher than 0.95 to save energy, the constant power is less affected by the change of input power supply, the stable output lamp voltage and filament current can prolong the lamp life and reduce the stroboscopic of the lamp, and it has various protections such as open circuit, short circuit, overvoltage and overcurrent. Some intelligent electronic ballasts can set time periods to adjust the light. You can join QQ 1433429986*** to study together.
