Color Temperature
Color temperature refers to the color of light emitted by a source and is measured in Kelvin (K). It ranges from warm tones to cool tones. Lower color temperatures (around 2000K to 3000K) produce warmer, more yellow or orange light, similar to the light of an incandescent bulb or candle. Higher color temperatures (5000K to 6500K) produce cooler, bluer light, similar to daylight.
- Warm Light: Ideal for creating cozy, relaxing environments, such as living rooms or bedrooms. Warmer light (2700K - 3000K) has a calming effect.
- Cool Light: Best for task-oriented areas like offices or kitchens, where sharper, more focused lighting is needed. Cooler light (5000K - 6500K) promotes alertness and focus.
- Neutral Light: A balanced white light, often used in commercial spaces, that replicates daylight (around 4000K - 4500K), helping to maintain a neutral atmosphere.
Color Rendering Index (CRI)
CRI is a measure of a light source's ability to accurately reproduce the colours of objects compared to natural light. It is measured on a scale from 0 to 100, where a CRI of 100 means that colours under this light source appear the same as they would under natural daylight. A higher CRI indicates better color rendering.
- High CRI (90+): Best for applications where color accuracy is critical, such as art galleries, photography studios, or retail stores. High CRI lighting ensures that the true colors of objects are visible.
- Medium CRI (80-89): Suitable for most indoor environments like homes and offices, providing good color reproduction without the need for perfect accuracy.
- Low CRI (below 80): May distort the appearance of colours, making them appear washed out or dull. Not
ideal for areas where visual clarity is important.
