One of the first things they teach in interior design school is how to plan for lighting. Good lighting really does make such a difference. No one wants to feel like they are under interrogation lights while eating dinner!
When we made over our kitchen last year, we planned on adding over and under cabinet lighting. Fortunately, my husband is very experienced at electrical work so this was an easy DIY for him. He says this is relatively easy and low voltage for anyone who has some basic electrical knowledge. If not, hire out. Safety first.
We used LED tape lights. We first measured out the sections where we needed the lighting to go, and then cut the lights accordingly. Be sure to follow the included directions on where to make the cuts.
We started with the upper cabinets, because that is where our outlet is. He drilled holes between each of the sections to run the wires through. He also drilled holes between the upper and lower cabinets to make a path for connecting the top to the bottom.
He used connectors to connect the sections of tape lighting together. The LED tape lights have a sticky backing which makes them easy to attach underneath of the lower cabinets.
