|Manufacturer Name||SURFACE CIRCULAR 350 18 W 4000 K WT|
|Budgetlight warranty||3 Years|
|Average Lifetime (h)||30000|
|Energy efficiency class||A|
|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)||1440||
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.

A light with a sensor can turn on automatically. Depending on the sensor it has, this can be whenever it detects motion or a lack of light, or both.
