The Intersection of Art and Science in Lighting Design

Lighting design is increasingly recognized as a blend of artistic and scientific principles, focusing on creating functional spaces while also enhancing aesthetic appeal. It is vital to understand how various light spectrums can impact our well-being throughout the day. For optimal health, lighting must adapt to situational needs, with lower-level, warmer hues being more appropriate in the evening. A successful lighting design layers different types of light, such as ambient and task lighting, to create a harmonious environment that supports both functionality and health.
