Effective lighting in small bedrooms involves layering ambient, task, and accent sources to create a balanced, spacious feel. Replace traditional bedside lamps with wall-mounted plug-in sconces positioned around 56 inches off the floor to save surface space. Use soft, warm LED bulbs to enhance cozy mood lighting. Incorporate accent lights, like small built-in shelf lighting, to highlight decor and add depth. Maximize natural light during the day with light, sheer window treatments. Thoughtful lighting choices prevent clutter and make small rooms inviting and dynamic.
