What Are LED Lights?

Light-emitting diodes, also known as LEDs, are semiconductor devices that emit light when an electrical current passes through them. Where incandescent light bulbs use electricity to heat their tungsten filaments until they emit light, LED lighting uses that energy to produce light directly, generating almost no heat. LED lights are fast becoming the videographer’s go-to. They provide easy portability with a battery power supply and charger, rather than an AC adapter that needs a wall outlet.
