Here is a comparison of LEDs, compact flourescent's, and conventional incandescent light bulbs based on the light output of a typical 100 watt light bulb. This comparison uses the high average lifespan of each type of bulb and is based on current power consumption prices on the Nova Scotia Power website. The cost of ownership over 10 years includes bulb replacement cost.

The term LED stands for Light Emitting Diode. Modern electronics relies heavily upon LED light bulbs. For instance, LEDs transmit information from remote controls, are used in traffic lights, digital LED clocks, flashlights, and to form images on jumbo television screens.
