Hafele has several aluminum channels that are made to recess. Some come in specific lengths with lights already in them, several are designed for use with the tape. For 3/4" thick bottoms there is one that lays flat and protruded 1/16", another tilts slightly toward the backsplash so it sits proud 1/4" at the front. All come with diffusers.
They also have several pucks that recess.
The hard part with recessed is locating the wires.
AS LWO suggested there are a number of nice looking ones that can be exposed.
I just finished a white high gloss slab project where we had the doors set lower than the box, ordered solid stock with a bevel on the back, set the solid stock behind the doors and mounted the light rail to it. Advantage is easy and simple installation, clean look both open and closed, cleaner and cheaper than recessing the bottoms of the cabinets.
Downside- you give up 3/4 to 1" in height inside the cabinet and of course you have to be working with a company that does that.
