Electricity usage of a LED Light Bulb

LED or the light-emitting diode light bulb is a good energy efficient option for lighting, often beating out CFL light bulbs in power efficiency and longevity at a similar price. A typical cheap (60 watt equivalent to incandescent) LED light bulb is advertised as providing 800 lumens, lasting up to 10,000 hours at 10 watts.
