I put them in, I think if you get a bulb that is close to the comparative wattage of a regular bulb, you won’t notice much of a difference.
My bills have remained steady. The thing that was not factored in is that you may save on your bills IF the energy rates stayed the same. Every year my energy rates go up. So staying about the same in my bills despite the rate increases, I have to believe they are helping to keep my costs from going up more.
The other part about it is that I like the fact they can light my house without 90% of the energy they use being turned into heat energy. If they could make a regular bulb that had the same efficiencies and most of the energy it used was not converted to heat, I’d consider that bulb too.
I really did like them; however, they were much more expensive; but did last longer.
