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 3 of 6: Install LED Strips

Carefully peel back the protective backing from the adhesive on the LED strip. Align the strip with the prepared edge of the first stair tread and press firmly into place, working from one end to the other. Ensure the strip is straight and centered. Repeat this process for all stair treads, following the planned layout. If the LED strips need to be cut to length, do so only at the designated cut marks on the strip.
