A properly designed house will have a conduit at
chair rail height.
This topic is suddenly relevant to my interests. I went to the recyclers and came home with a 'finished composite 4x4' eight feet long. It's a 1x4, a 2x2 and another 1x4 laminated together with a full 4x4 end.
This will be the header for my carport extension, mounted with the 2x2 trough facing down. I want to fill it with a string of RGBLEDs. I can run them white all year long and then change to waves of color a few nights before Christmas.
What do you recommend for an eight foot string of lights?
