LED - Super Bright Blue 5mm (5000MCD).

Super bright 5mm Blue LED.   This type of LED is known as a "super bright blue" LED and has a brightness of 5000 millicandela (mcd). It is typically used in electronic projects and devices where a bright, blue light is needed. LEDs are a type of semiconductor device that emits light when an electrical current is passed through it. They are often used in electronic circuits because they are small, efficient, and long-lasting. The specific color of an LED is determined by the materials used in its construction, with different materials producing different colors of light.
