How to Install Kitchen Unit Lights

Install kitchen unit lights to add a new dimension to the decor of your kitchen. These lights supply light directly under the wall cabinets to which they are secured. They provide lighting directly over the work area for food preparation. To choose the right kitchen unit lights, measure the distance between the bottom of the bottom shelf and the bottom of the cabinet fronts. The most common light fixture for this project is puck lights, which are available in kits and are among the easiest to install.

  1. 1

    Make a mark 1 inch behind the face frame (cabinet fronts) under the bottom shelf. Center it between the bottom of the bottom shelf and the bottom of the side of the cabinet.

  2. 2

    Drill a 3/8-inch hole through the cabinet sides. This allows the wires for the kitchen unit lights to connect to each other while hiding the wires at the same time. Clean any splinters from the holes with sandpaper.

  3. 3

    Measure the distance between the sides of the cabinet on the bottom shelf and mark the centre. Center the light fixture on the mark and install it as close to the front of the cabinet as possible with 3/8-inch screws.

  4. 4

    Locate the receptacle for supplying the electricity to the kitchen unit lights. Feed the wire for the lights through the holes in the cabinet sides. Connect the wires to the lights according to the manufacturer's instructions.

  5. 5

    Staple the wires to the bottom of the bottom shelf; use staples about 3/8 inch longer than the thickness of the wire. Secure the transformer to the bottom side of the cabinet next to the receptacle with 3/8-inch screws. Connect the wires from the lights to the transformer, and plug it in.

Tips and warnings

  • Choose lights with frosted lenses to prevent hot spots in and under the cabinets.
  • Do not install lights that produce high heat under cabinets.
