Australian Lighting standards

The basic requirement for adequate lighting is that the work must be easy to see and the light comfortable to the eyes.Illumination is measured in units of LUX - lumens per square metre. led panel light and led downlight is very popular.

Suitable light levels based on Australian Standard AS 1680 - 1990 Interior Lighting are: -

•General background 200 Lux
•Routine office work (typing, filing) 400 Lux
•Work with poor contrast (proof reading) 600 Lux

Appropriate lighting is important to minimise unnecessary eyestrain and to ensure that an appropriate posture is maintained. For example when individuals find it difficult to see what they are working with they tend to lean closer, which results in an awkward posture. Excessive light levels (greater than 1000 lux) can cause headaches.

Helpful hints
•The OHS Unit can perform light measurement assessments. To arrange an assessment contact OHS Administration on 9385 1565

Glare and reflections

Glare and reflection can result in eye discomfort and strain. Glare and reflections can occur from overhead lights, poor lighting positioning, and type of lighting or external light sources (eg. windows). To check for reflections place book or object between light source and desk or monitor to determine whether reflection is reduced (Australian Standard AS 1680.2.2 1994 ).

Helpful hints to eliminate or reduce glare and reflections
•Utilise blinds to control light from windows.
•Re-orientate workstation to minimise the amount of light falling on work area. Workstation should be at right angles to light sources.
•Overhead lighting should be fitted with glare reducing diffusers. The light should fall from the side rather than the front to avoid reflections on the work surface.
•Windows should be to the side of the user if possible, not directly behind or in front of the screen.
•Tilt the screen so that reflections are directed below eye level.
•Cover screens with an anti-glare screen. It is important to be aware that the use of anti-glare screens can reduce the brightness of the monitor, so they should only be used when the above strategies are not effective.
