I just re-did a galley kitchen. Mine is in sunny SoCal and has greenhouse-style windows over the sink and in the breakfast area so we have good ambient light during the day.

My approach was a 14" central solar tube (which I LOVE!), a small fan with lights in the breakfast area, under cabinet lights along the long wall, a pendant low-wattage light over the sink (I don't like harsh light), two recessed cans & a light kit in the solar tube for the evenings, and the four xenon lights that are incorporated in the hood on the short cooking wall that end in a peninsula.

This has worked well for me. I prefer warm and diffuse light. Because of that I find a combo of the breakfast area light + either the sink or range light (depending on where the activity is) provide good soft light. I rarely use the recessed lights and the 60 watts (all CFL) I get from the solar tube. They're wired in together and illuminate the room to bright midday which is plenty of light for any taste.

I think the thing to think of when you plan lighting is a variety of options so you're not stuck with one-size-fits-all. Also, think of what the activity is in the dark hours when you'll want lights. In my kitchen the fridge-stove-sink triangle turns into the sink-stove-table triangle.

PS For my under cabinet lights I used Kichler linear lights which consist of a wired strip into which you insert as many light units as you like wherever you like. I really love them.
