How to power LED with 120 volt A/C supply
Thanks to all for the input, I finally figured it out. I connected the ground/neutral directly to the cathode of the LED and took the hot/120-ground to a 27k resistor in series to a IN4007 diode tied antiparallel,anode of led to cathode of diode, and it works fine. Thought it would need some...- ShadyRaider

How to power LED with 120 volt A/C supply
OK, First of all thanks to all for trying to help this simple "neophte" with this problem. I am lacking knowledge in this area.....that is why I am here. By having a antiparallel connection does this mean simply having the anode from LED connected to cathode of diode, and cathode from LED to...- ShadyRaider

How to power LED with 120 volt A/C supply
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...- ShadyRaider
