Light colour is also known as colour temperature and is expressed in Kelvin (K). You can choose from:

• Extra warm white (1700K - 2700K). Atmospheric light. For places with a relaxing character.
• Warm white (>2800K). Neutral and soft light. For common areas such as halls, corridors, foyers.
• Cool white (>3400K). Fresh and natural light. Good for focus/concentration in schools and offices
• Daylight white (>5000K). Equals natural daylight. Suitable for situations where a lot of light is needed.

The colour code is a combination of the colour rendering index (CRI) and the colour temperature (K). The first number refers to the CRI (1 = very poor colour rendering, 9 = maximum accuracy). The second and third numbers refer to the colour temperature. For example, a light with a colour code of 830 has very good colour rendering and produces a warm white light.

The colour rendering index (CRI) indicates how accurately colours are represented under a beam of light. The index goes from 1 to 99, with a CRI of 1 being the poorest and a CRI of 99 being the best possible. Be careful not to confuse colour rendering with colour temperature (K).

Lumen (lm) is the term used to describe the total amount of visible light emitted by a light source. The higher the number of lumens, the brighter it is.
