The last time I was at Home Depot, they were selling the 100 W equivalent 5500K (CF) bulb for $12 -- but were selling an entire desk lamp fixture with Happy Eyes or Bright Eyes bulb of 6000K quality for $20.
With the the quality of light from these bulbs, I don't need reading glasses. I think most vision problems are due to poor lighting quality and these reading CFL seem to be the best quality lighting around -- producing virtual sunlight quality without the heat.
I like the LEDs for portable lighting -- and since they require so little power to run, those with the hand crank can provide lights for substantial time enough to perform most tasks.
Lighting really needs to move into the space age. The incandescents are little more advanced than open fires.

The next big thing - actually taking LED's into the space age - will be quantum dot LED lighting.

The problem with current LED's is the design of the LED's themselves. It's difficult to replicate a standard light bulb throw for everyday household and office applications. And the output has been lacking. If they can get quantum dot LED lighting to work and be practical, it will not only make LED lighting practical for every day use, it will open up different lighting possibilities most people haven't even thought of.
