Office lighting

When you look out of the window you will notice that winter has arrived. Consequently, days are getting shorter and nights equally longer. To brave the darkness and be able to work productively after the twilight hour, suitable artificial lighting is inevitable.

Then again, too much light – whether it may be of an artificial or natural source – is an enormous strain as well, as it can glare or reflect in an unfavorable way. Additionally to these objective factors everybody has individual light requirements. Thus, the ideal light intensity is not only dependent on the premises, but also on the age of a person and the activity that is pursued. Consequently, you need other light intensities for screen handling than you need for manual labor.
For manual tasks, experts recommend a luminous intensity of 500 to 1500 lux. In contrast, the advice for pc work is an illumination of 500 lux sharp, to make sure to keep all the contrasts on the screen. To be able to bring the numbers into line: Pure sunlight at noon is perceived to be about 100 000 lux, street lights on the other hand have a luminance of 10 lux. Anyway, you should make sure to have a good balance of natural and artificial light at your desk. Ideally, the natural daylight should be used where possible – for example with the help of adjustable solar shading devices.
A quite simple way to meet the individual light requirements in the office and to keep the productivity on a high level, is to set the level of illumination at 500 lux and provide desk lamps at the individual work stations. When fixing ceiling suspended lights you should make sure to reduce glare by placing the pc workstations between the lighting devices and not directly underneath.
Some suppliers of lighting devices are: Glamox Luxo, Trilux, Tobias Grau and Herbert Waldmann.To simulate different lighting scenarios before rearranging your office you can use pCon.planner
