Measure the space under the kitchen cabinets where you want to install the LED lighting. Order the appropriate number of flexible light strips for your project.
Attach mounting channels to the wall under the cabinet as close to the cabinet as possible so the lighting is hidden from sight when standing normally in the kitchen. Use screws to anchor it to the wall, or clean the wall with rubbing alcohol and use liquid nails to hold the channels in place. Alternatively, attach the flexible LED light strip directly to the wall with the attached tape.
Pull the paper covering from the back of the strip exposing the adhesive. Either tape the strip directly to the wall or mounting channel, leaving the end loose until you connect the next section. Continue adhering the strips to the wall, connecting the sections to each other.
Snap the lens cover over the LED lighting strip starting at the far end and gently pushing the cover in place along the mounting channel.
Connect the end of the strip to the driver strip and then to the wall adapter plug. Plug in the lights.
