LED lighting is a rapidly advancing technology that uses energy more efficiently than conventional lighting but also can help save energy in indirect ways, such as with air-conditioning costs. LED lights use small, powerful sources of light that illuminate when electrons move through semiconductor materials. They shine in only one direction and only produce a small fraction of the heat of fluorescent and incandescent lights. This not only makes them more eco-friendly than other lighting options but LED's have a much longer lifespan as well.
Because LED lighting is more energy efficient their use reduces utility bills. As of 2011, an Energy Star-qualified LED bulb has an average operating cost of $1 per year. Compared to annual costs of $1.20 for an Energy Star-qualified compact fluorescent bulb, $3.50 for a halogen incandescent bulb and $4.80 for a traditional incandescent bulb. In addition, because a Energy Star-qualified LED bulb has a longer life there is much lower turnover of bulbs in your house. LED lights last a minimum of 15 times longer than a traditional incandescent bulb to a maximum of 25 times longer. LED lighting is clearly the most eco-friendly lighting option available today, well the 2nd most (sun!)...
