Ikea Undercabinet Lighting

The past few weeks have been a lot of two steps forward / one step back in the kitchen. While tidying up the remaining boxes of kitchen stuff I came across the cabinet lighting, and thought “huh I wonder when I’m supposed to install these.” I’ll tell you…. before you secure the wall cabinets. Oops.

It took a while to figure out how to route all the wires. Then I had to unscrew and take down some of the cabinets, cut holes where appropriate, re-hang them, and then use a combination of fishing line and my tiny hands to fish the wires through. When the cabinets were off the wall I threaded fishing line through the holes. I secured it with painters tape to keep it from falling out, and then once the cabinets were mounted I taped the ends of the wires to the fishing line and dragged them through.

Installing the  Omlopp lights was kind of a pain. There are 6 light strips under my cabinets and getting them all lined up right was surprisingly tough, despite measuring everything. This is one place where oblong mounting holes that let you adjust would have been greatly appreciated, but weren’t provided. I also found that the directions are sort of backwards. They tell you to install the cord cover first, then the mounting strip,  then clip the light to the mounting strip. But it’s much easier to clip the cord cover loosely over the cord, mount the light, and then just stick the cord cover to cabinet wherever it lands.

I think most people put the transformers and cords above the cabinets. I don’t have the clearance up there so everything is going in the cabinet above the stove and I’ll put a shelf near the top to keep it mostly hidden away. There’s already an outlet in that cabinet for the microwave so the lights will be on the same circuit.

There are also two round recessed lights inside the end cabinet (which has glass doors and shelves). With the cabinet on the ground I used a 2.5″ hole saw to cut holes and then pushed the lights up into them with the cord coming out the top. I used some painter’s tape to keep the wires from flopping around and getting in the way when we put the cabinet back on the wall.

I opted for the plug-in lights because I didn’t want to deal with hardwiring them in. The transformers they plug into have a remote, but the transformers buzz whenever the remote is off. They don’t make noise when the light is on. I don’t know if I just got two duds, or if this is a widespread problem with the Ikea Ansulta transformers. Hopefully replacements will fix the problem.

I’m happy with how they turned out but a little discouraged by the buzzing issue, which I suspect is due to poorly engineered circuits in the transformers. I don’t mind losing the dimmer if it means getting ridding the noise.

  1. Can I ask you a question? I am not sure if you are in Canada or the US but did you have your electrical inspected? We are in Ontario and ESA is telling us we cannot put the outlet in the cabinet… This is messing up our whole lighting plan! Backsplash is already tiled as it was our last inspection and now we may have to forgo all the under and cabinet lighting! Not happy about this. Any ideas? TIA! Very helpful blog! Your kitchen looks wonderful!

    1. I’m in the US and it passed inspection, however that was an existing outlet and I’m not sure whether it was a “ok because it’s fine in this area” or “ok because some other idiot put it there.” Since the only layout change we made was moving the fridge I only needed a plumbing permit for plumbing the ice maker to the sink and replacing the sink / dishwasher.

  2. We have a pretty blend hat it will not pass inspection with a plug in, not hard wired is there a piece that we can buy to allow it to be hard wired?

    1. Not from Ikea. You would need to talk to an electrician who is licensed in your area to discuss options that comply with your local codes.

      1. I have the same issue.

        Few months ago I replaced the light bulbs. They started to burnout again within a few weeks.

        My set is four in series.

        I’m taking them apart next weekend.

        1. Pulled from under cabinets and replaced with halogen bulbs with halogens.

          Let the set run overnight on my living room floor, face up, no glass on top. Normally there are two bulbs that go out immediately, within 4 hours of replacement. All lights are running fine after 24hours.

          Suspect it’s overheating. Ordered some xenon. I’ll see about the color profile and if they overheat and post again.

  3. We had under cabinet and inside cabinet lights installed a month ago. Beautiful! Today half of them went out. Any ideas why it happened or how to fix them?

  4. Did you continue the Omlopp lights under the corner cupboard?
    I am just installing an Ikea kitchen using Metod wall units and Omlopp lighting.
    The instructions state to mount the Omlopp lights 26.5cm (10 7/16″) from the rear edge of the wall unit.
    When I’ve followed this line all the way to under the corner cupboards, the two 40cm Omlopp lights under the corner cupboard overlap by around 2cms where they meet.
    I’ve tried contacting Ikea but they have been of no help at all.
