Standard LEDs, also known as through-hole LEDs, are a type of LED (Light Emitting Diode) device that is available in various shapes, sizes, and colors. This type of LED is composed of an anode and a cathode, which are connected with a wire connecting them. The current passes through the anode, then through the diode, and then through the cathode, resulting in an electrical current that directly illuminates the diode. Unlike other types of LEDs, standard LEDs are generally brighter than their surface mount counterparts, and are usually used for industrial and commercial applications. They are typically used in commercial lighting, indoor and outdoor lighting, and commercial electronics. Standard LEDs are also very common in consumer applications, such as bayonet light fittings, desk lamps, and small torches.
