Do leds use ac or dc

WebAC LED vs. DC LED. Abstract: An AC LED is an LED that operates directly off of AC line voltage while a DC LED uses a driver to convert the line voltage to direct current (DC) power. A light emitting diode (LED) is a … WebLEDs are commonly powered by AC, which gives the maximum possible output. DC uses a battery to power the LED and has a very dim light output. DC has the advantage of being able to throw light in all directions, making it perfect for lighting up large areas.
