Yes / No / Maybe
What I tried to do was have my electrician run wires to the basement directly under my kitchen, but even though the distance was not great (20' or so), I could not get it to work. I assume there was too much voltage/amperage drop off. Instead I ended up buying a flat extension cord (the end that plugs into the outlet lays flat) and just laying all the controls on top of the cabinets so that only the thin wire was running down from the small power supply (ballast). Because we have some crown molding on top of the cabinets you can't see the wires up there. I used double sided sticky tape to tape the "control box" in the slim area between my cabinets.
I assume I could have purchased a more heavy duty power supply for the basement, but these lights are expensive enough already. I still have the wire, so maybe if there is a need I'll go with a bigger power supply down the road, but as long as it works I'm fine for now.
One other tip. When you trim the lights, put a section of electrical tape at the end you cut. I put the lights in a defuser channel and I shorted out a controller when the cut end pushed out past the plastic and made contact with the metal channel.
