The operational life current white LED lamps is 100,000 hours. This is 11 years of Continuous operations, or 22 years of 50% operation. The long operational life of an led lamp is a stark contrast to the average life of an incandescent bulb, which is Approximately 5000 hours. Using LEDs would virtually eliminate the need for routine Bulb replacement.
The key strength of LED lighting is reduced power consumption. When designed properly, 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 cent / Kilowatt hour . $88 will be spent on electricity costs. of the $88 expense, $70 will have been used to heat the room, not light the room.
If an 80% efficient LED System had been used, the electricity can would be $23 per year-there would be a cost saving of $65 on electricity during the year. Realistically the cost savings would be higher as most incandescent light bulbs blow within a year and require replacents whereas LED light bulbs can be used easily for a Decade without burning out
