Increased energy-efficiency (via LED lighting) means that LED's will not only save you energy, but money as well. In fact, the average 60-watt LED light bulb will save you significant cash over its useful life through energy savings and avoided replacement costs. So you're putting money in your pocket and because you are using far less energy, you are not depleting nearly as much of the Earth's resources. In essence, you are going green. There are so many benefits to switching to LED's, it's time you give it a try.
