Adding lights to stair risers is beneficial since it can be hazardous negotiating stairs especially at night. Staircases are often enclosed so light them from the sides or embed lights in the risers as a design element.
Don’t limit lighting to downlights. Depending on the location consider wall sconces or uplighting to create a softer ambiance and avoid potentially harsh downlighting that can cast ominous shadows.
Lighting design is all about the strategic placement of light and matching the perfect light source to its intended function. Indirect lighting pulls focus adds texture and layers the sight line.
