Energy savings equal energy bill savings and one way to save energy in your home is to switch out your old light bulbs with new LED bulbs. But when you scan the price tags of LED light bulbs you probably end up with some sticker shock. When I was converting my home bulbs, I had to look closely at cost versus benefit as we had more than 60 bulbs that could be replaced.
It can be hard justify spending on average $10-$12 each. To help justify and stomach the expense I found a great LED light savings calculator, which helped me learn that by replacing all the bulbs in my home I could recoup the investment in about 3 years, which is a lot less than the life-expectancy of the bulbs!
