I think you got that backwards Mike, generaly going to DC is much more efficient. for example changing your furnace from a 120V fan to a 12V unit will save you about 25% on your power consumption due to your furnace. if you go with a varable 12V fan the savings are even more.
the main reason for having AC is the ability to change its voltage easy and it carries over long distances better.
I think the man drive for developing AC Line voltage driven LEDs is cost. no ballast needed, can be dimmed with a simple wall dimmer from home depot ect.....
