Using smart lighting in DIY home decor transforms your space instantly by layering different light sources. Start with ambient lighting to create overall brightness, add task lighting for activities, and finish with accent lights to highlight art or architectural features. Incorporate dimmers and smart bulbs for adjustable brightness and colors. This approach balances function and mood, boosting comfort without renovations. For example, use plug-in sconces to add light without wiring. Smart lighting increases room usability while making your decor personal and flexible.
