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.
