We all know what a LED (light-emitting-diode) light is, and according to the U.S Dept. of Energy it is one of today’s most energy efficient and rapidly-developing lighting technologies. Now, what is an investment? An investment is the allocation of money or some other resource (asset), in the expectation of some benefit in the future (return).
In a recent cost analysis based on a price survey by the Consumer Federation of America, it was determined that the typical American family uses at least 20 indoor light bulbs throughout their home. Now let’s do a comparison of just one 60-watt incandescent, halogen, and LED’s use in a household for 10 years.

Now multiply these findings by 20 and see why LED lights used in everyday normal settings can provide great savings, or return your investment over a ten year period. It’s a no-brainer.
The prices of the bulbs are based on GE bulbs at major retailers. The life expectancy of incandescent and halogen bulbs is 1 year, and the life expectancy of a high-efficiency LED bulb is 10 years.
