Measure the intended area for LED lighting in order to determine the number of LED strips necessary for the project.
Check the load on the power supply in watts and milliamps per strip according to the LED manufacturer's package information and verify the strip can be used with your power source.
Temporarily fit the strips at the project site to determine the exact lengths needed, cutting the strips to make a proper fit. Lines are marked on the strip indicating where cuts can be made safely.
Solder the power connector wires between LED strips, using a soldering gun, following the manufacturer's instructions. Verify the positive and negative polarity of all connections.
Attach the LED strips to the project surface, using the mounting holes on the strips. Some strips come with brackets and screws for mounting.
Connect the LED strip to a switch power supply whip and then plug the other end of the whip into the 120V power outlet.
Put silicon sealant on any cut LED ends to prevent corrosion. Allow the sealant to dry four to six hours.
Spray a clear acrylic coating over the LED strips to seal electrical pads and connections, while also helping to prevent damage from moisture and corrosion. Let the coating dry thoroughly overnight.
