This 5mm blue LED is sold singly for circuit boards, hobbyist projects and educational purposes. LED stands for light-emitting diode, a semiconductor light source that gives off light when an electrical current passes through it.

When electrons in the semiconductor recombine with electron holes, energy is released as photons, producing visible light. The band gap of the semiconductor material determines the colour.

An LED lasts a long time and consumes minimal power.
