Layered lighting is important because it enhances ambiance and functionality without permanent changes. Using plug-in sconces, picture lights, and floor lamps adds warmth and dimension that peel-and-stick wallpaper can’t provide alone. For example, a plug-in sconce hung at sixty-four inches creates balanced illumination and highlights art or wall texture. Layered lighting makes temporary upgrades feel complete and tailored while keeping installation renter-safe and deposit-friendly.
