CCT (Correlated Color Temperature) is measured in Kelvin (K) and describes the color appearance of white light produced by a lamp.
Lower CCT (e.g., 2700K–3000K) → Warm white light
Higher CCT (e.g., 5000K–6500K) → Cool or daylight white light

CCT tells you the color of the light.
CRI tells you how accurately the light renders other colors compared to natural light.
Example: Two lights can both be 5000K, but one might make colors appear more vibrant (higher CRI) than the other.

| Incandescent bulbs | ~2700K | Traditional warm light, being phased out |
| Halogen lamps | 2800–3000K | Slightly whiter but still warm in appearance |
| LED Warm White bulbs | 2700K–3000K | Energy-efficient with a wide range of options |
