‘Color Temperature’ refers to the general color tone of a white light source. Lighting with a lower color temperature will emit warmer orange-yellow tones, while higher color temperatures will emit cooler blue tones. Color temperatures of 2,700K and 3,000K both fall within the range typically associated with traditional filament bulb lamping and are considered ideal for residential and hospitality applications.

‘CRI’ stands for ‘Color Rendering Index’ and measures a light source’s ability to show colors realistically as compared to natural daylight. For example, filament bulb lamps are typically 95-100 CRI, while a fluorescent lamp can have a CRI as low as 60-65. So the higher the CRI value, the more natural colors will appear.
