Lux levels are also known as illumination. The effectiveness of illumination can be affected by factors including light quantity & quality, contrast, amount of flicker, shadows, and intensity of glare.
The larger the room/area, the more lumens the luminaires need to give in order to create sufficient light levels. These can change when other factors enter the equation, such as natural light and the purpose of the room.
When it comes to offices and other workplaces, it is the employer’s legal responsibility according to Regulations 1992 to provide “suitable and sufficient lighting” to his employees.
Insufficient light (low lux levels) is a common cause of fatigue and muscle strain. This becomes more likely if the exposure is consistent over longer periods of time. On the other hand, excessively high lux levels can distract and cause distress or even impair people’s vision.
