The LED bulb (~50,000 hours) longer life expectancy is superior to the life expectancy of the incandescent bulb (~5,000 hours). When lighting devices are located in inaccessible places, additional savings is achieved using LED’s, reducing the periodic bulb higher replacement cost and labor.
There is no comparison between the cost of LED lights vs. traditional incandescent. With incandescent bulbs, the true cost of this bulb is the periodic labor, time, and cost to replace bulbs. This is significant, especially where there are large numbers of installed bulbs and inaccessible locations. For office buildings, towers, and skyscrapers, maintenance costs to replace bulbs can be significant. These replacement issues are virtually eliminated with LED’s.
The key strength of LED lighting is reduced lighting and a/c power consumption and the 10x longer life expectancy reducing maintenance labor. When LED's are designed properly, ~80% efficiencies are achieved vs. incandescent bulbs operating at ~20% efficiency. Realistically the cost savings is higher as most incandescent light bulbs blow out within a year requiring replacement whereas LED light bulbs last 10 times longer before replacement.
