We recently replaced all the light bulbs in our home with LED bulbs. What a huge difference, I love it and we don't have to wait for the bulbs to warm up and get brighter. They do not put off heat the way some older bulbs do so that is a cost savings also. We were on a roll so we also bought a 70" LED TV, we had a LCD TV and you could walk by it and feel the heat coming from it. So far we have seen between 40.00 - 60.00 savings on our electric bill.
