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.
Candles also offer wonderful sparkle and set a distinctly relaxing romantic tone. Just make sure you keep them well away from any flammable objects such as towels and hair and never leave them unattended.
Adding lights as decorative elements helps set a mood in a space. Provided that general lighting is already installed using lights instead of wall art can be a decorative way to provide ambient lighting.
