|Energy efficiency class||A||
The European Union has drawn up guidelines for energy labels for lighting. The energy efficiency of lamps and luminaires is expressed in classes (A to G). Energy label A is the most efficient and energy label G the least. The energy label is also stated on the packaging of a product.
|Average Lifetime (h)||50000|
|Colour temperature (Kelvin)||4000K - Cool White||
The colour temperature refers to the colour produced by a light. It's measured in Kelvin (K) and ranges from warm white (1700K - 3000K) to daylight white (6500K). Neutral white (3100K - 5000K) is mainly used for general lighting applications.
|Colour Code||840 - Cool White||
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.
|Colour Rendering (Ra)||80-89||
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).
|Light Output (Lumen)||640||
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.
|Beam Angle (degree)||40|
|Luminous Efficacy (Lm/W)||49|
|Cut out (mm)||86|
An IP rating consists of two numbers: the first number (0 - 6) relates to the level of protection against solid objects (including dust), the second number (0 - 8) relates to the level of protection against water.
