    Glossary LED light

    semiconductor device that converts electricity into visible light

    An LED light, or light-emitting diode, is a type of lighting technology that uses a semiconductor to convert electricity into light. Unlike traditional incandescent bulbs, LEDs are highly energy-efficient, have a longer lifespan, and produce less heat. They are commonly used in various applications, from household lighting to medical treatments, including therapies for skin conditions and hair growth.
