Correlated Color Temperature (CCT), measured in Kelvin (K), influences the lighting environment within classrooms. Different CCT values create distinct ambiances, ranging from warm, yellowish hues at lower Kelvin values (e.g., 2700K) to cool, bluish tones at higher values (e.g., 6500K). For instance, a 3000K light source provides a comfortable and inviting atmosphere, while a 5000K source offers a brighter, more stimulating setting.
Appropriate lighting in educational settings contributes significantly to student well-being and academic performance. Studies suggest that specific color temperatures can impact concentration, alertness, and visual comfort. Historically, incandescent lighting dominated classrooms, producing a warm, yellowish light. The advent of fluorescent and LED technologies broadened the available spectrum, enabling finer control over color temperature and energy efficiency. Choosing the right CCT can minimize eye strain, enhance visual clarity, and potentially improve focus and mood.
