LED still only makes sense to save money if the lights are on more than about 8 to 12 hours a day. The payback time is otherwise pretty long. For example, spending $30 on an LED bulb, to save a few dollars a year is ok, but it's more cost effective to stick to a compact fluorescent these days.

GE has a new 40W incandescent replacement bulb, that uses only 9W. Costs about $28. Can get in online at amazon. Philips has a 12W LED too, but best not exposed.

At energysipp.com, we've being doing a lot of research on LED, as it's the future. We recommend to buy only one first, and try it for light quality and dimmability. Often they're best in a ceiling recessed fixture, or a table lamp that has a shade to soften the color.

Within a year or so, LED prices will have come down, making them cost effective for most lights at home.

Best,
