Specifications Ledvance TruSys Performance Rail system 70W 11200lm - 840 | Wide Beam Angle
|Manufacturer Name||TRUSYS PFM 70W/4000K W LEDV|
|Energy efficiency class||G|
|Colour temperature||4000K - Cool White||
Light colour is also known as colour temperature and is expressed in Kelvin (K). You can choose from:
|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)||11200||
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.
|Luminous Efficacy (Lm/W)||160|
