HOW TO MEASURE LIGHT AND LUX LEVELS....


Itís vitally important to know how to measure light & lux levels in the workplace or in your home;

bad lighting can be hugely detrimental to your business. Not enough light (or low lux levels) may cause fatigue, muscle strain, and costly mistakes in work, particularly if an employee or colleague is exposed to insufficient lighting over long periods of time.

The same is true for excessive light (or lux) levels. Glare and reflected light can distract an individual

and impair his or her vision, which is particularly dangerous when a job requires the workerís full attention,such as working with machinery or hazardous chemicals.


A simple calculation has been devised to work out LUX levels.


Lux level = total light output (lumens) / area (square meters)
total light output = lumens per fixture * number of fixtures
