[TenTec] station power supplies

[Cecil]

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...
