The new "hybrid" incandescents use exactly the same filament material, but encase a slightly thicker filament in a glass tube. The light is indistinguishable from the old incandescent bulbs. Compact fluorescent (curly) bulbs put out light with different colors, however, the higher quality bulbs are pretty good — some of the cheapos were awful — and are even more efficient. LED bulbs are by far the most efficient and come in a wide array of light "temperatures" now which do a pretty good job of mimicking incandescent light (look for "warm white"), Philips and Cree are good quality.
Just for historical reference, the light bulb efficiency bill was bipartisan and signed into law by GWB although Rush Limbaugh liked to blame it on Obama.
I installed all LED lights in my house in December 2012. I changed my first light bulb — in a fixture that is used nightly — this summer.

I've had bad luck with LED's, but thanks for the tips.
