    A: LED stands for Light Emitting Diode. 
2. Q:  What is the difference between an incandescent bulb and an LED?
    A: Incandescents create light by filament. When power is applied, the filament glows, generating heat, in turn, producing light.
         LED is more efficient and energy saving by creating light though a "cold process"- When power is applied to semiconductors (usually gallium, arsenic and phosphorus), they're stimulated by the movement of electrons; thus creating photons, the light that is visibly seen by humans. 
3. Q: Why do LEDs use such little power?
    A: LEDs produce very little heat and do not use filaments, so the energy transfer to light is more efficient.
