Install Flexible LED Strip Lighting

What happens in this clip

Begin by planning the route for the flexible LED strip lights along the underside of each stair tread. The video demonstrates routing the warm white LED strip horizontally along the back edge of the tread, then curving it downwards around the side of the riser, and continuing under the subsequent tread. This creates a continuous flow of light. Secure the LED strips to the wooden substructure of the treads and risers. This can be done using the adhesive backing typically found on LED strips, or for a more robust attachment, use small mounting clips. Ensure that any connecting wires are discreetly managed and hidden within the staircase structure, possibly by drilling small, circular cutouts or channels in the risers to allow the strips or wires to pass through without being seen. The goal is to achieve a clean, uninterrupted light line along the underside of the treads. Finally, connect the LED strips to a suitable LED power supply/driver and an optional dimmer/controller, ensuring all electrical connections are safe and insulated.

About the full video

This project involves installing flexible LED strip lights beneath the treads of a staircase to create a modern, ambient lighting effect. The lights are carefully routed to follow the contours of the treads and risers, providing indirect illumination for safety and aesthetic appeal.

Step 6 of 6: Install Stair Lighting (Optional)

Plan the placement of your LED strip lights. Typically, they are placed just above the riser on the tread nosing or along the stringer. Cut the LED strip to length as needed. Clean the surface where the lights will be adhered thoroughly. Adhere the LED strip lights, connecting them to their power source and transformer according to the manufacturer's instructions. Ensure all wiring is neatly managed and secured, ideally concealed within the staircase structure or along its edges. Test the lights to ensure they function correctly.
