I am looking for a way to power a LED from a 120 volt A/C source. I have seen some suggestions that it could be done with a resistor only and some saying a diode is needed as well. I am using a 2.2v max V-F, and 35mA max I-F LED and want a simple "power on" indicator light from the 120 volt A/C line. Do I need a diode/resistor on both the anode and cathode of the LED? I tried a suggestion I read on this site that said a 27-47k resistor would work by it self, but it pops the resistor and LED instantly. Any suggestions would be greatly appreciated
Thanks, ShadyRaider

"It LOOKS like it turns 'off' by shunting the power to the resistor so that any power savings are imaginary."

For some reason I find that discovery to be hilarious. Thanks for sharing.
