As with sound too much or too little can have a profound effect on how we work or our general wellbeing.

In open plan environments the ambient light needs to conform to ‘The Schedule to the Workplace (Display Screen Equipment) Regulations 1992 (Statutory Instrument 1992 No. 2792)’ which requires that: 'Any room lighting or task lighting provided shall ensure satisfactory lighting conditions and an appropriate contrast between the screen and the background environment, taking into account the type of work and the vision requirements of the operator or user.'

This basically sums up the minimum standard and offers wide remit to lighting layout. On an individual basis we advocate the use of personal lighting to add extra light to an individuals workspace – this can be achieved with the use of a good desk lamp.

The other area often overlooked is ensuring that sunlight glare or shadow does not cause a computer user to incline their body or head to better view their screen.

A monitor arm will allow the desk user to rotate or move the screen out of the way of such shadows or glare and allow users to maintain good posture.
