Before You Begin

Under cabinet lights are very easy to install, but a little preplanning will make for a better job. These units can be strung together, but don't connect more than 20 of the 8 watt 13-inch units or 10 of the 20-inch 16 watt units. Also the manufacturer recommends that the units be spaced at least 1-1/2 inches apart, but no two units should be more that a maximum of 5-feet, 9 inches apart. The minimum distance between fixtures is 1 inch.

These instructions are for installing one or more Ultra Light 13-inch fluorescent cabinet lights by Westek.

  • Step 1 : Locate the fixture for mounting

    Locate the fixture for mounting

    Remove the plastic diffuser by gently pressing down on the arrows and sliding it forward (D). Hold the fixture under the cabinet and position it under the front lip or trim of the cabinet. This location will enable the light to reflect off of the back splash and down onto the counter top, minimizing the potential for glare. Mark the screw holes with a pencil ©. Also mark the opening edge of the Power Link connector door on both ends of the fixture. (A)

  • Step 2 : Wiring multiple fixtures

    Each light is packaged with a length of SPT-2 cord and a crimp-on plug. Use this power cord wire to make end-to-end interconnections. Connections must be made before the fixture is mounted.

    To calculate the length of the cord joining the fixtures measure the spacing between the fixtures and add an additional 1-1/2-inches that will go into the Power Link of each lamp. If the lights are mounted 6-inches apart the cord should be cut to 9-inches (6" + 1-1/2" + 1-1/2"= 9")

    Wiring multiple fixtures Cut the length of SPT-2 interconnect cord for connection between fixtures. Then make an additional cut in the insulation between the two wires 1/8-inch up from each end. The ribbed side of the SPT-2 cord must be pierce by the silver-plated contact in the Power Link connector.

    Wiring multiple fixtures On each connection, slide off the Power Link cover, push cord down into the cavity and bend it to 90 degrees. Press the cord down into the channel so the metal contacts pierce the cord's insulation and make contact with the wire.

    Press cord into the channel to make contact Use your thumb or a screwdriver to press the wire down onto the connection. Slide the cover back into the fixture.
