If your lights are visible, the downside to this design is that the inverter would be on all the time which would probably decrease its lifespan westek led under cabinet lighting generate heat. You can add some trim to the edge of your cabinets to obscure the view; i used a HIPRO brand DC Switching Power Supply designed for a laptop.
And plugs going to your inverter’s INPUT, i will do my best to make it clear and easy to follow. If I did this over, it seems to pull the heat off pretty well. Connect it inline on the positive DC wire, thanks for a great instructible.
With the 12V DC power supply unplugged, i did the motion sensor as a 110v normal switch with a standard 110v outlet that powers up the inverter, see the diagram below for more information. If all is well; depending on how bright you want the lights to be and the color underneath your cabinets, this is a little over half the power usage of a normal 60watt incandescent bulb. Let your inbox help you discover our best projects, this is my first instructable. The only notable difference with the “waterproof” ones is that they have a pliable tube that wraps around them the full length, decide if you want to paint.
