While it is true that LED lights typically require a higher initial investment than incandescent lights, the cost of LEDs has been coming down as they become more popular. But the real savings come from LEDs' amazing energy efficiency and durability. Because LEDs use far less energy than incandescent bulbs and are far more durable, they will be much cheaper to use over the long run.
Because LED lights convert most of their energy into light rather than heat, they will use far less energy than incandescents to produce the same amount of light. That means you can use LEDs of a far lower wattage to create the same amount of light as incandescents. The lower wattage will instantly translate into savings in your electric bill and continue to save you money for as long as you use them. In addition, if you live in a hot climate, LED lights will not be heating up your rooms as much as incandescents, saving on your a/c bills.
LED lights also boast a far longer lifespan compared to incandescents. In fact, they can last 10 times as long as incandescents.
Further, LEDs are more durable because of the way they are made. LED lights are basically tiny chips enclosed in plastic, while incandescents depend on extremely thin wires encased in glass. As a result, LED lights are far more resistant to breakage, vibration, shaking and temperature changes.
Because they last far longer and consume far less energy than incandescents, LED lights are also much better for the environment as well as your wallet. You will require less electricity from polluting power plants, and you will be throwing fewer items away for landfilling. In addition, LEDs are made of nontoxic materials and contain no mercury. So when they do ultimately die, you will not be polluting the environment with toxic chemicals when you dispose of them.
Besides all their economic and environmental benefits, LED lights also provide you more design latitude. Because they can be created to offer a range of colors, from the warm whites typical of incandescents to the cool whites similar to automotive halogen headlights, LEDs can be used in a wide range of environments and for many purposes.
