The operational life of current white LED lamps is 50,000 hours. This is 11 years of continuous operation, 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 1,000 hours. If the lighting device needs to be embedded into a very inaccessible place, using LEDs would virtually eliminate the need for routine bulb replacement.Massive Savings
There is no comparison between the cost of LED lights vs. traditional incandescent options. With incandescent bulbs, the true cost of the bulb is the cost of replacement bulbs and the labor expense and time needed to replace them. These are significant factors, especially when there are large number of installed bulbs. For office buildings and skyscrapers, maintenance costs to replace bulbs can be enormous. These issues can all be virtually eliminated with the LED option.Triple Energy Savings
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. Compared that with incandescent bulbs which operate at about 20% efficiency (80% of the electrical energy is lost as heat).What Does That Savings Look Like?
In real money terms, if a 100 W incandescent bulb is used for 1 year, with an electrical cost of 10 cents/kWh, $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 cost would be $23 per year – there would be a cost savings of $65 on electricity during the year.Imagine: Changing A Bulb Once A Decade
Realistically the cost savings would be higher as most incandescent light bulbs blow out within a year and require placements whereas LED light bulbs can be used easily for a decade without burning out.
