I'm trying to develop a flasher circuit for an aircraft warning light like the one shown at https://flightlight.com/products/obstruction-lights-controls-faa-l-810/. The light will be powered with normal 120VAC providing 15 amps. I'd like to use transistors (BJTs, MOSFETS, thyristors, DIACs, TRIACs, etc.) to cause the light to flash (turn on and off at a given frequency).
Along those lines, I found several examples of transistor-based flasher circuits online, such as this one: https://www.electroschematics.com/4488/diac-controlled-led-flasher/ However, those circuits seem to all be intended for use in powering LEDs, which, I assume, have a lower current draw than the light I'm intending to use. Along those lines, I have a couple of questions:
1/ Will the circuit I linked to above work with the light I'm powering? If so, what modifications do I have to make to accommodate the higher current levels in the light I'm using?
2/ If this circuit does work, how do I modify the frequency of the flashing? I know it's possible to control that frequency by changing the values of the resistors and capacitor, but I don't remember the formula to do so.
3/ In the diagram for the circuit I found, it looks like the capacitor voltage has been set to 100V, presumably due to the value of the resistors. How do I calculate the voltage for that capacitor for a different resistor value?
Thanks for your help!
