Whats difference between incandescent and LEDs?
A. Incandescent bulbs create light by the use of a filament. When power is applied, the filament glows and generates heat, which in turn produces light. LEDs create light through a “cold process”. When power is applied to the semiconductors (usually gallium, arsenic and phosphorous), they are stimulated by moving electrons, which creates photons. These photons are the light that can be visibly seen.
