WebScience. Traditional incandescent lights don't care. In fact you will get very similar brightness if you give them 120 volts AC, and 120 DC. LEDs are a completely different story. A single LED typically wants somewhere around 2 volts DC across it (how much voltage it wants depends on its colour), and the amount of current it wants through it ... WebHalf-wave rectification may not by itself be sufficient to power an LED taillight from an AC system. As was mentioned, there is no voltage regulation occurring with this simple rectification. Simple LED taillights contain biasing resistors to set the amount of current that will flow through the LEDs, and the biasing resistor's value assumes a ...

"WebJul 7, 2024 · The "16V" AC transformer will give that voltage when passing its rated current (bell current). If your lamp draws less current then the voltage will almost certainly be somewhat higher, say 18V (rms). Given that an indicator LED drops ~ 1.8V - 3V (depending on its colour), that leaves at least about 15V rms to be dropped across a current ... " - Can leds be powered by ac
