I'm not sure I can do that unless you expand on what you mean by "for home lighting" as you evidently don't mean what I guessed at in response to your last posting - absolute brightness. Do you mean beam pattern, colour temperature, or something?
Actual light output.
Trouble with led's is that when lighting up your house, they are no more efficient than tungsten lamps, and less efficient than Halogen. It's getting their, and rapidly but Led tech has some way to go before it could be compared to flourescent lighting!
Depends what you mean by efficiency, I would assume you mean the amount of energy they use.
They are far more efficient than any other type of light bulb in this regard. The drawback is that the light output hasn't quite reached practical levels yet.
When you say "less efficient than halogen" do you mean less bright than halogen?
Also, for people worried about using cfl's with dimmers.... there are dimmable versions available, ask a specialist lighting company. I know Megaman do some. These will become readily available in the fullness of time, like everything else.
