Can Dc LED run on AC?

Most LED lights are designed to run on direct current (DC), but they can be powered by alternating current (AC) with the help of additional components. LED lights themselves are essentially diodes that emit light when current flows through them in one direction.

When you connect an LED to an AC power source without any modification, it will typically flicker because the direction of current alternates between positive and negative cycles in AC. To make an LED compatible with AC, a rectifier or a bridge rectifier is often used to convert AC to DC. This ensures that the current flows in one direction, allowing the LED to function properly.

Some LED lights come with built-in rectifiers or drivers that perform this function. They can accept a range of input voltages, including AC, and internally convert it to the DC needed to power the LED. However, it's important to check the specifications of the LED light you're using to ensure it can handle AC power if that's what you plan to provide.
