Exposed stair lights are a great way to bring life and color to your home staircase. Without any aluminum extrusions, the best approach for installation is usually to attach LED strips in a hidden manner underneath the stair tread's overhang. This allows for the LED light to shine downward, creating a beautiful glow effect while hiding the light source from view. It can be a creative way to add subtle lighting and enhance the ambiance of your home staircase.
