I would never suggest DC power distribution...I was thinking along the lines
of a conversion at the home panel to low voltage DC for use with more simply
designed LED lighting. I don't have first hand knowledge because I haven't
been willing to make the leap, but have been told the power supplies built
into the rear section of the LED replacement bulbs get very hot. They do
have the appearance of a heat sink. Just thinking if that could be
eliminated it would probably increase efficiency....of course all it might
do is move the heat load to the garage...

Don't forget Ohm's Law. The reason we use AC for power distribution is
that it can be transformed to the voltage needed to keep wire loss low.
Low voltage DC is fine if copper is free. :)
