What is the difference between an incandescent bulb and LED?
Incandescent creates light by the use of a filament. When power is applied, the filament glows and generates heat – which in turn produces light. LEDs are just the opposite. LEDs create light through a ‘cold process’. When power is applied to semiconductors (usually gallium, asenic and phosphorous), they’re stimulated by the movement of electrons, this creating photons. Photons are the light that is visibly seen by humans.
