LEDs use less energy than incandescent bulbs because diode lamps are more efficient and energy efficient than filament lamps. LED bulbs use more than 75% less energy than incandescent bulbs. At low power levels, the difference is even greater. Bright LED floodlights use only 11 to 12 watts while producing light output comparable to 50 watt incandescent bulbs.
What is an LED light bulb?
Technically, an LED light bulb isn't a light bulb -- LED stands for "Light Emitting Diode." They are tiny semiconductors (diodes) wrapped in plastic to protect the components and focus the light. According to Dictionary.com, a diode is a "semiconductor device with two terminals that normally only allows current to flow in one direction." Current enters the anode (+) and exits the cathode (-). LEDs don't even have a filament like a light bulb.
