I'd love some lighting tips from those who have built, or live in, timberframes. I am adding a 12x34 one-story, three-bay, flat-roof addition onto the south side of my 30x34 two-story timberframe. Both house and addition have 8.5 ft ceilings.

We underlit our original house, and I would like to avoid that for the addition, but don't have much insight on how to do this right other than to run an excess of wires and track and work it out after the fact.

I'm thinking of centered ceiling fan/light combos in each bay, plus paired runs of track lights along the joists within each bay.

Any good rules of thumb, success stories, things to avoid, or other tips? All thoughts appreciated.
