How to build Mains Operated LED Circuit Schematic

Here is a simple and powerful LED circuit that can be operated directly from the AC 100 volt to AC 230 Volts mains supply. The circuit can be used as mains power locator or night lamp etc.. The resistor R1,R2 and capacitor C1 provides necessary current limiting. The circuit is sufficiently immune against voltage spikes and surges.parts D1 = 1N4007 D2 = 1N4007 D3 = 1N4007 D4 = 1N4007 R2 =
