Background: The operational life of an LED bulb is over 50,000 hours. This is 6 years of continuous or 12 years of 50% operation. The long operational life of an led bulb is a stark contrast to the average life of an incandescent bulb, which is approximately 5000 hours. But the key strength of LED lighting is reduced power consumption. An LED circuit will approach 80% efficiency, which means 80% of the electrical energy is converted to light energy. The remaining 20% is lost as heat energy. Compare that with incandescent bulbs which operate at about 20% efficiency and 80% of the electrical energy is lost as heat. In real money terms, if a 100 Watt incandescent bulb is used for 1 year, with an electrical cost of 10 cents/kilowatt hour, $88 will be spent on electricity costs. Of the $88 expense, $70 will have been used to heat the room and not light the room. If an 80% efficient LED system had been used, the electricity cost would be $23 per year - there would be a cost savings of $65 on electricity during the year.
