LEDs (light-emitting-diodes) are a light source powered by electricity and are commonly used in deck lighting, landscape lighting, and other interior and exterior uses.
LEDs only emit light when electricity is applied in the forward direction. Because of this, an LED can only illuminate while the AC current cycle is running in the LED’s forward direction. When an AC current is applied, the LED might appear to flicker.
To avoid this, the AC current can be converted with a DC transformer at the beginning of the circuit so that the LED receives a DC current. An LED can also be fitted with a bridge to only pick up the forward cycles of the AC current.
LEDs generally have a longer life than standard filament light bulbs, with over 50,000 running hours, whereas a standard filament bulb generally only lasts 10,000-25,000 hours of running time.
