Re: AC power to LEDs

Lenore Edman

First, do not hook them directly to AC! You will need to use an AC to DC converter. It is most efficient to start with a low voltage, something like 3 V if you can find it, but likely 4.5 V or 5 V will be easier to find. Yes, you will need to use current limiting resistors for each of the LEDs. You can read about how to determine the resistor value here:
