I'm going to add over/undercabinet lighting to my kitchen following the example project Pete Dokter's did on the SparkFun "According to Pete" video series (link below). I'm pretty much going to copy this exactly. I'm going to use the same LEDs, the FemtoBuck LED driver, and the same aluminum c-channel. I have an old laptop power brick that can source 19.5V and 3.3 amps which is plenty for 3 or 4 parallel branches if they each draw 350mA. I'll wire a couple switches and hide them in or under the cabinets. I don't intend to add in dimming yet but I can at a later date if I want to.
