The illumination Survey or Light Assessment or Lux Level Monitoring is conducted to identify either too bright light and glare, or low or flickering light to avoid potential detrimental effect. Subsequently risk assessment is performed to improve employees’ safety. Adequate and proper lighting has a great impact on performance and efficiency of the employees at the workplace.

As the lighting quotient is directly linked with the visual environment and allows the workforce to see, move and perform tasks efficiently and safely, it is integral to the conducive environment at the workplace.

Illuminance is a common parameter while studying Illumination Measurement. It defines or measures the amount of light falling on the unit surface area of the workplace, and its unit is lux (lx). It is used to evaluate the capability of lighting for seeing an object.
