Hi guys. I have heard about LED bulbs that they can save your money by spending less electricity. Well, we already having CFL bulbs at our home which was popular in past for the same reason. Now people are saying LED bulbs are even more good. But we haven't used it yet. So what do you think? Should I upgrade my all bulbs from CFL to LED? What is the difference? I mean is using LED can make too much difference in compare to CFL?
