How Much Power Savings using LED's?

120V LEDs are not not as reliable and not cheap either.

The only good 120V LEDs IMO are Philips. They're not cheap but they went from nearly $50 three years ago to $15 now. Cree just jumped into the 120V market too and I think the competition is what drove Philips prices down to its present price (price dropped from $30 to $15). The Philips bulbs are reliable. I have three on my front porch that go through 115F summers and 20F winters. I usually replace incandescents once a year on the porch lights. Even the CFL's didn't last more than a year out there although MEX tells me GE's are better. The Philips are still going strong after two years.
