Great pendant lights Ross. They have a Japanese style look to me. I was wondering how you were going to conceal the romax.
I built 3 Japanese style pendants and posted them on LJ.
We had a cabin by a lake and had the T&G ceiling. It was 1-1/2” Douglas Fir. I concealed the wires with a light brown vinyl square tube with double sided tape on it I got from Lowes.
Your wire in the peak will be concealed well with your idea.
Those electrical boxes match you style. Where did you get them?
