I have a 100 - 240v ac to 5v DC switching adapter. Is it possible to intercept the voltage just after the rectifier and get 120v dc. I have read different things, the consensus seems to be that switching adapters rectify 120vac to 120vdc then run it through a transformer to drop it to the needed voltage, then through some filtering and regulation. Is this correct?
I am trying to make a simple led light, if I use 120 vdc I would need less resistors. I believe.
