What is Lux:
This is used as a measure of the light level as perceived by the human eye.
Objective:
The lighting of an interior should fulfill three functions. It should:
1. Ensure adequate light levels at the appropriate time of day,
2. Facilitate performance of visual tasks, and
3. Aid the creation of an appropriate visual environment.
Negligence of testing:
1. The lights can make a difference to the way you feel and can even affect your health. Our bodies need a good quantity of light at the right intensity and at the right time of day to act as cues for our internal body clock.
2. An improper light level can impact risk of developing illnesses and disorders, such as headache, weak eyesight and depression.
