Lighting Assessment
Ensuring that the illuminance levels are adequate to prevent visual fatigue.
NOHH Ltd undertakes workplace lighting assessments to evaluate adequacy and compliance within operational environments. With decades of lighting experience, this page explains assessment criteria and how to arrange a lighting survey with an expert.
Why Carry Out Lighting Tests?
Lighting is often overlooked in workplace health and safety, yet poor or inappropriate lighting can have significant consequences. Inadequate lighting is linked to eyestrain, headaches, and fatigue, and can contribute to reduced productivity. More seriously, poor illumination increases the risk of accidents, particularly in factories and warehouses where changes in layout can leave areas in shadow.
When Lighting Becomes a Problem
Indicators of poor lighting include squinting, leaning in to read or view objects, or shading the eyes from glare. Problems may arise from more than just light intensity — issues can also result from:
Glare from reflective surfaces
Poor positioning or orientation of light fittings
Unsuitable type of lighting for the task
Shadows caused by the location of lights relative to operators or machinery
Flicker or stroboscopic effects from certain light sources
Movement of personnel, vehicles, or equipment affecting visibility
