What Does Appropriate Light Levels Mean?
Appropriate light levels, within the context of workplace health and safety, are one of the factors considered when evaluating a workplace's lighting ergonomics. An appropriate light level is one that is neither too bright nor dim for the required work, and is balanced in relation to other light sources such as windows or computer screens in the surrounding space.
WorkplaceTesting Explains Appropriate Light Levels
An appropriate light level, or illuminance, is essential to a safe and healthy work environment. Proper lighting of each working area improves visibility and prevents headaches, eye strain, and vision fatigue. Insufficient light can lead to accidents and lowered productivity.
Appropriate light levels should be set to prevent both shadows and glare while also avoiding stark transitions from light to dark. Light levels in the workplace are measured in foot candle (ftcd, fc or fcd) or lux units. One foot candle is equal to one lumen per square foot, while one lux is equal to one lumen per square meter.
An average office lighting level may range from 250 to 750 lux, depending on the specific tasks being performed in the space.
