The lux (symbol: lx) is the SI derived unit of illuminance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watt per square metre, but with the power at each wavelength weighted. levels within office spaces is kept below 400 lux, while SANS 204 recommends a lighting level of 300 lux for low risk commercial space. Operating in the range between 300-400 lux will provide sufficient lighting for conventional office tasks while not wasting energy 1. Record illuminance levels (foot-candles or lux) in various spaces using a handheld light meter: Office light levels should be taken at desk level (standard is 30 inch above the finished floor [AFF]). Hallway measurements should be taken at the floor level and restroom measurements should be taken at counter height OH&S level of room lighting for an office environment is a minimum of 320 Lux* while the recommended light level for producing accurate and consistent screen based graphic work is between 32 Lux to 64 Lux. *An explanation of Lux and Lighting standards in subsequent sections. What follows is an explanation of measuring light using Lux value The office environment has changed considerably since the previous version of this lighting guide, LG7 Office lighting, was published in 2005.
