CCT, or Correlated Color Temperature, exists in the realm of lighting technology, specifically as a gauge of how yellow or blue the color of light emitted from a light bulb appears.
Understanding CCT
CCT is measured in Kelvin (K) and typically ranges from 2200K to 6500K. The Kelvin scale helps us understand the "warmth" or "coolness" of light. Lower Kelvin values (e.g., 2700K) indicate warmer, yellower light, similar to what you might expect from an incandescent bulb. Higher Kelvin values (e.g., 5000K) represent cooler, bluer light, akin to daylight.
Practical Examples
- 2700K (Soft White): Ideal for bedrooms and living rooms, creating a cozy and inviting atmosphere.
- 3000K (Warm White): Suitable for kitchens and bathrooms, offering a balance of warmth and brightness.
- 4000K (Cool White/Neutral White): Works well in offices and workspaces, providing a clean and focused light.
- 5000K-6500K (Daylight): Best for task lighting and areas where accurate color rendering is important.
Key Takeaways
- CCT measures the color appearance of light.
- It is measured in Kelvin (K).
- Lower Kelvin = Warmer (yellowish) light.
- Higher Kelvin = Cooler (bluish) light.
