Why is LED lighting still so expensive?

Which is probably one reason they're so prevalent in federal buildings.

Use two, oppositely polarized so they light on both sides of the AC sine wave?

I have CFLs in the majority of my house and there are places I just refuse to have anything but an incandescent. A big issue with CFL's in my area is the cold temperature. Maybe not a big deal in warm climates, but in a place like MN, Try putting one of them up as a porch light in winter and it will be dimmer than a flashlight bulb.
Older and cheap grade models also suck with the lag after turning them on. That split second irritates the crap out of me. Especially with that light on the top of the staircase down to the dark basement.
And with having a little Kid, I wont have CFLs on any of my lamps where my kid can reach. The glass is more brittle and im sure my son could snap a bulb in his hand with little effort. The fact that they are filled with mercury makes the adventure of a broken bulb even more fun.
As for LED's....I haven't used them because of the price. I have a hard time paying more than 0.99 for a light bulb. I love my LED worklights, but the spectrum of light produced is very uncomfortable for my eyes. Do home LED Light bulbs produce a better spectrum of light?

Good quality LED lamps like the Phillips L Prize bulb haven't been on the market for very long. CFLs still have better light output and cost significantly less than LEDs.

Depends on which LED bulb you buy. The L Prize bulb gives off a warm white light(2,700K) like an incandescent.
Also, here is a lamp cost comparison chart that shows LEDs aren't quite ready for prime time yet.
