   diy.stackexchange.com › questions › 6409

   26 lis 2016 · I want to also power (in parallel) a set of 12V LED lights which (of course) require a 12V DC supply. Is there a simple method of AC->DC conversion that I can use? I am pretty handy at electonics so I could make a simple converter given the correct guidance.
