I dont know how much it will save the electricity, this LED new tech does not have Bulb that is last. Eventually, I know you paid more than you pay now. $15 for a bulb is not really a buy.
Yeah most LED light bulbs are still at a premium compared to CFL. The energy saved won't pay for itself over the life of the bulb. The other benefits for the cost are that instant full brightness and dimmable. Supposedly the color too.
We, however, actually prefer the CFL warm up instead of being somewhat blinded from rooms with many [bright] lights. Besides we turn on the lights at dusk and keep most of them on until going to sleep. We do have a few LED light bulbs but mainly since they were a better buy than CFL being candelabra base and the energy saving is nearly half..
