Lighting Question #1: What is colour temperature?

The colour or warmth of white light is ranked on a scale, The Kelvin scale, the warmer the colour the lower the colour temperature. A 'warm' colour temperature is typically 3,000K or less. A 'cool' white light bulb commonly has a colour temperature of 4,000K and higher on the Kelvin scale.

Lighting Question #2: What is CRI?

CRI stands for Colour Rendering Index, this is measured from 0-100, with a perfect 100 indicating that colours of objects under the light source appear the same as they would under natural sunlight. All Zico Lighting light bulbs have a CRI of 90 as a minimum, this creates great colour rendering.
