“How Many Under Cabinet Lights Do I Need?”

If you are about to embark on a kitchen remodel and are installing under cabinet lights, follow these guidelines to determine how many fixtures you should purchase.

First, measure the length of the “cavity” under your cabinet where you are going to place the fixtures.

If you are installing puck lights…

For a 6-10 inch cavity measurement (in length), use 1 puck light.

For 11-18 inches, use 2-3 puck lights.  For 19-26 inches, use 3-4 puck lights. For  27-34 inches, use 4-5 puck lights.  For 35-42 inches, use 5-7 puck lights.  For 43-50 inches, use 6-8 puck lights.

The "cavity" is the area underneath the cabinet that forms a hollowed-out space.

If you are installing linear (also known as strip) under cabinet lights…

Try to “fill up” your cavity with the longest fixture that will fit.  The goal with linear lights is to keep your countertop and backsplash uniformly lit, so you want to match that cavity measurement as closely as possible.  Usually, under cabinet lights are sold in standard increments of length.  For example, you might be able to choose between 8in, 16in, 24in, or 32in.  In that case, if your cavity measures 18 inches long, be sure to select the 16 inch fixture rather than the 8 inch fixture.

There are some exceptions to the standard increments of length rule: Our Xenon Low Voltage Light Strip is totally customizable and may be ordered in any length measured to the nearest whole foot.

      Thanks for your questions! If you’re looking for some sleek xenon puck lights, I’d suggest either these versatile xenon triangle lights or these very low profile steel xenon puck lights.

      When it boils down, there are really 3 main reasons individuals choose xenon over LED: 1) Xenon has a perfect color rendering index of 100, meaning its light doesn’t distort the colors of any objects around. Some people have complaints about the quality of LED light, and they dislike the color. 2) Xenon lights are extremely easy to dim, so you can change the look of your room at will. LEDs can be dimmable, but the technology is newer and not as reliable. 3) Since LEDs are a newer technology, they tend to be more expensive upfront than xenon lights.
