Kelvin – the colour temperature The colour temperature of light – whether we experience it as warm or cold – is measured in Kelvins (K) and indicates the colour of a light source. The picture illustrates the colour temperature of light ranging from 1,000 to 10,000 K. It is important to choose the right light source based on the light’s intended purpose. Whether the light is required for work purposes, background lighting or to create cosiness it is an important factor to consider when choosing the correct light temperature. Directions for use: Indoors, residential Indoors, office/industrial Outdoor lighting Light colour: Kelvin: Warm white Below 3,300 K Neutral white 3,300 – 5,300 K Cool white Above 5,300 K Symmetrical and asymmetrical lighting In work situations where light is important for your wellbeing – and thus your job satisfaction and effectiveness – we distinguish between symmetrical and asymmetrical lighting. Asymmetrical lighting If your primary work tool is a computer, you need a lamp with asymmetrical lighting. The light is angled using advanced reflectors to prevent annoying reflections and unpleasant glare. Symmetrical lighting A work lamp with a symmetrical beam distributes the light evenly on the work surface. This can be an advantage, for example, at conference tables, in shops, at work stations where manual work is done etc. LIGHTING GUIDE
