Lamp inrush current suppression circuit
Inrush current is the main reason for failure of the lamp. The circuit can be used to limit such current. But when the filament reaches normal operating temperature, it can provide the lamp with a normal current. This circuit also applies to low pressure pilot lights. But as long as the voltage and current is no more than certain ratings of the transistor, any kind of light bulb can be used.
